I need to install a modified version of a formula (MPI version of hdf5 by adding options that are no longer supported).
Now the problem is that I do not want to symlink this library in the /usr/local/... tree, but would just like to compile and keep it aside in a /usr/local/Cellar/hdf5 directory.
Is it possible?
it looks like you just need to add
keg_only "it conflicts with other hdf5 libraries"
to the ruby formula

I currently have some c++ libraries that i would like to implement and build in ROS using catkin workspaces. My method so far has been to let each library be its own package, but I've recently run into a problem of circular dependencies with the packages. My approach to fix this has been to implement the libraries within a single package, but i somehow wish to keep the libraries separated and i therefore wonder if it is possible to structure the include folder for a ROS c++ package with subfolders?
The idea would look something like this
--catkin_ws
--src
--my_package
--include
--library_1
someheaderfile.h
--library_2
someotherheaderfile.h
..
--src
--library_1
somecppfile.cpp
--library_2
someothercppfile.cpp
CMakelists.txt
package.xml
I guess my main concern lies within breaking the catkin structure needed for proper compilation.
Thanks!
Solved:
As long as you properly structure your CMakeLists.txt with respect to the guide presented here: http://docs.ros.org/melodic/api/catkin/html/howto/format1/building_libraries.html, and your subdirectories lie within include/my_package/ everything works fine.
I am trying to install GLscene but getting problems with the source file locations.
It says in the install instructions to add the GLscene source directories into the global library path in tool/options/Delphi options/Library, which I have done but it has no effect.
I can add the source directories into each package project directory and it then compiles, but I would rather have it accessible globally.
The GLscene library items I have entered are,
C:\Users\Andy\Documents\Embarcadero\Studio\Projects\GLScene_VCL\Source
C:\Users\Andy\Documents\Embarcadero\Studio\Projects\GLScene_VCL\Source\Shaders
C:\Users\Andy\Documents\Embarcadero\Studio\Projects\GLScene_VCL\Source\DesignTime
Which are all correct,
anybody know any reason why the compiler can't find the files in these directories?
The compiler will search for source files on the library path. Note that there are separate library paths for different targets, e.g. Win32, Win64 etc.
If you have source files that cannot be found, then they are not in the library path that you specified.
Personally I don't like the approach of using search paths for source files. I like everything under my project directory so that I can check out from my VCS and have everything I need to build right there. A search path based approach makes serious development very difficult because you cannot maintain branches. What if you have old versions to maintain that use old versions of your libraries?
Well this is a bit late but it could help someone else.
Try and add the paths to both the Library Path and the Debug DCU Path.
Recent Delphi versions have different build configurations for Release and Debug and my guess is that the Debug configuration only searches in the Debug DCU Path.
I'm want to compile meshlab(http://sourceforge.net/p/meshlab/code/HEAD/tree/) and put the generated file outside the source directory to keep the source clean. Is it possible to just specify a build directory as the way in cmake?
The answer in this post Qmake and Make using separate folders for sources and headers, requires to modify the .pro file and doesn't work in my case. Users may want to specify the build dir path as they like, right?
I think what are trying to do is a QMake Shadow Build. This question about Manually Configuring Shadow Builds in QMake should help you.
There are bunch of helper filess in 'iPublicUtility' folder of several audio related Apple sample codes, such as aurioTouch:
http://developer.apple.com/library/ios/#samplecode/aurioTouch/Introduction/Intro.html
I can build these samples fine. But whenever I create a new project for testing and include the files from 'iPublicUtility' folder, I get:
'CADebugPrintf.h: no such file or directory ... ' error in 'CADebugMacros.h' file.
I made the settings of my test project to coincide with Apple samples, but this error is
not going away. Any suggestion?

Thanks all.

select the Target, open the Build Settings pane, search for "Preprocessor Macros". Leave the fields blank (I've got rid of a DEBUG entry)
I used the answer provided by Justin and it worked fine, until I installed Xcode 4.3.1 and the problem came back.
Currently I solved this by downloading CADebugPrintf.h and .cpp.
I found the 2 files at this link:
http://svn.perian.org/trunk/CoreAudio/PublicUtility/
Cheers.
i have three distributions of Xcode installed.
the file exists in all three.
1) verify that the file exists on your system.
2a) add a search path to your project for the PublicUtility directory
or
2b) add the header to the target's "copy headers" build phase
depending on how many depends you have for these files, you may want a more reliable approach (which exists). one (fairly) safe/easy way to do this if you use a lot of the audio technologies and sources is to add its parent dir's parent dir to your search paths or source trees (recursively).
another way is to add it to a shared build settings file.
you could also copy a specific release someplace, then add that to your search paths. just be aware that the sources get updated somewhat regularly, so you'll have to update it when it's a good time for you. in this case, you'll should change your project references as well.
Edit: Adding the search path (2a)
One way to add a search path (assuming Xcode tools are installed at : /Developer/):
1) In Xcode (3), select the target.
2) cmd+i (get info)
3) select the "Build" tab of the info window
4) enter HEADER_SEARCH_PATHS into the search field
5) if the value is not defined at this level (e.g., it is not bold), then set the value to /Developer/Extras/CoreAudio/PublicUtility/ $(inherited)
if it is already defined at that level, then add /Developer/Extras/CoreAudio/PublicUtility/ to the list of directories to search (the value).
if you want to search the library recursively, use /Developer/Extras/CoreAudio/**. this may be useful when building AUs, or other projects which require the AU includes and PublicUtility includes.
Same problem, but seemed to have fixed it by downloading from the link below and adding in the missing CADebugPrintf.h and CADebugPrintf.cpp files.
https://developer.apple.com/library/ios/samplecode/CoreAudioUtilityClasses/Listings/CoreAudio_PublicUtility_CADebugPrintf_h.html
I was having the same problem and downloading the files into the iPublicUtility folder did not solve it. I found the answer by accident while learning about .mm extension files on this page:
Objective C Project using C++ POSIX Classes
I renamed my implementation file with a .mm and the compiler errors disappeared. Hope this may help someone down the line!
I'm doing some Delphi (2010) work this summer, and I've stumbled upon this problem:
My project consists of reusable backend library and a bunch of GUIs that tap into its interface. In this circumstances I've decided to make the backend and GUIs separate projects within single project group (I hope my train of thought is correct). The problem is, how can I include units from the backend in a GUI project?
I've tried to modify Project Options > Directories and Conditionals but compiler still complains about being unable to find proper .dcu's.
Any ideas? Your help will be appreciated.
In D2010, the Directories and Conditionals in the project option refers to (and is specific for?) the resource compiler.
I guess what you are looking for is the Project Options->Delphi Compiler->Search Path
Search where the compiler is generating the DCU files. (2)
In project options you must add the source directory on you have de PAS files (1) or the directory where compiler generate de DCU files.
(1) In the "Search path" edit.
(2) This directory is the "Unit Output Directory" edit.
