I'm using Ubuntu 14.04, after installing LLVM & Clang, when i tap this in the terminal it reports the error:
wishfay#wishfay-virtual-machine:~$ clang -v
clang: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by clang)
And i check my libstdc++.so.6:
wishfay#wishfay-virtual-machine:~$ locate libstdc++.so.6

I want to know how can i get the GLIBCXX_3.4.20 .
According to the ABI page, GLIBCXX_3.4.20 is part of gcc-4.9.
You need to upgrade your version of gcc, or get a clang binary that supports your OS, or you need to build clang from source.

I have installed LLVM 5.0 on Windows 10 x64. When I call clang++ --version from cmd the message below is displayed.
clang version 5.0.0 (tags/RELEASE_500/final)
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\LLVM\bin
But when I call qbs setup-toolchains --detect in the resulting list neither clang nor clang++ is in. If I call qbs config --list profiles both clang and clang++ are not in the list. Am I missing something?
On Windows, the --detect option only looks for MSVC and mingw installations. Use the explicit mode instead:
qbs setup-toolchains C:\LLVM\bin\clang.exe clang
Recently I clean installed Yosemite 10.10.2
I also installed gcc using
brew install gcc
Now I'm trying to build and install python and openmpi from source because previously I've had problems with gfortran and clang.
So I did
brew install openmpi --build-from-source -verbose
brew install python --build-from-source -verbose
with variables and aliases:

Error: pkg-config 0.28 did not build
My understanding is that there is a conflict between clang and gcc-4.9 configuration.
I could temporally solve it doing:
brew install pkg-config
So it doesn't build if from source and uses clang configuration.
I see that Xcode is still in the Include and Library path, and I think this prevents linking with gcc-4.9.
How can I install pkg-config using gcc-4.9 only?
Problem solved after following this instructions changing:
typedef void (^dispatch_block_t)(void); // this is for clang
To
typedef void* dispatch_block_t; //this is for gcc-4.9

The solution was to use homebrew and, after that, run pip3.4
brew install GDAL
and, once installed,
pip3.4 install gdal
Had this problem today. Installed GDAL with brew and it failed with pip3. The solution was to make sure that the version you try to install with pip is the same as homebrew has installed.
So first install gdal with homebrew using
brew install gdal
You should be able to see the version that is being installed during installation. If you have already installed gdal before you can check the version with:
brew info gdal
For me this showed that the version of gdal brew installed for me was: 2.4.4
So then you can install the correct version with pip using
pip3 install gdal==2.4.4
This finally worked for me.
tl;dr
How can I compile Ada source code to a static library file suitable for apps on iPad targets running iOS to link against? (GCC is not a requirement. Solutions using LLVM or others are also welcome!)
I have a large library of portable Ada code that I would like to use in an iPad/iOS project. My host OS is Mac OS X 10.9 (running GCC 4.8.1 installed at /opt/local with MacPorts). To do this, I'm trying to build a GCC ARM cross-compiler with Ada support.
I am able to build a working GCC and GNAT that creates ARM executables, but I can't seem to build or install the Ada standard library, which is required for building my Ada code
The source packages I'm using:
gcc-4.8.1
binutils-2.24
libiconv-1.14
gmp-5.1.3
mpc-1.0.2
mpfr-3.1.2
The GCC build configuration:
$ bin/arm-none-eabi-gcc -v --version
Using built-in specs.

Test program to ensure its building ARM binaries:
$ cat told_unit1.adb told_unit1.ads

with Ada.Text_IO;
use Ada.Text_IO;
package body told_unit1 is

function double(x : in float) return float;

end told_unit1;
Then compiling the Ada code and inspecting it with file:
$ arm-none-eabi-gcc -c told_unit1.adb
$ file told_unit1.o
told_unit1.o: ELF 32-bit LSB relocatable, ARM, version 1 (SYSV), not stripped
And then when I try to bind the library object file it pukes:
$ arm-none-eabi-gnatbind -aO$ADA_OBJECT_PATH -Ltold told_unit1
error: "a-textio.ali" not found, "a-textio.adb" must be compiled
Going back to my GCC build logs, I found that libada (which I believe is part of GNAT) wasn't ever built. When I try to run make all-target-libada from the GCC build directory, it eventually tells me:

So at this point I'm way over my head and not really sure what to do next. It looks like I'm missing a C runtime library for ARM maybe?
Any help configuring GNAT/libada for ARM targets would be great.
Alternatively- is there a simpler way to link against Ada libraries from an Xcode iOS project?
Unfortunately, the answer is that there is no auto-magic tool to accomplish this. You can use tooling to validate the translations after the fact, but what you want isn't available yet.
I've had to deal with this same question in the past. A different answer would have dramatically changed one of my project's budgets, too. Perhaps someday.
Though I admit, I think there are ultimately enough incompatibilities that your source would need to be drastically altered - reducing the value of what you are looking to achieve here. In the end, the new investment is a bummer but will result in better source, if you can afford it.
I tried this:
Alan#Alan ~/mercury
$ gfortran -o mercury6_2.for
gfortran.exe: fatal error: no input files; unwilling to write output files

and:
Alan#Alan ~/mercury
$ gfortran -o mercury mercury6_2.for
