When i run intel pin under valgrind i get the following error:
ERROR: ld.so: object '/usr/lib/valgrind/vgpreload_core-x86-linux.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
ERROR: ld.so: object '/usr/lib/valgrind/vgpreload_memcheck-x86-linux.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
i have valgrind-3.10.1
with
dpkg -l | grep libc6
i get

We are using flatbuffer v1.3.0 and seeing error building flatc compiler.
Same error for flatbuffer version v1.3.0 to v1.12.1
Build is successful for version 2.0.0
Should we use a particular version of make to build the flatc compiler? If so how to do it?
Steps
git clone https://github.com/google/flatbuffers/tree/v1.3.0
cd flatbuffers

Flatbuffer requires a specific version of clang to compile the 1.12.1.
Installing the required version.
sudo apt-get install clang-6.0 lld-6.0 clang-tidy-6.0
use update-alternatives to link the clang.

This is not really trivial on windows. I performed the following steps to pull this off:
Install visual studio 2019
Install gstreamer vs2019 edition with developer headers
Install Ninja-build
Install meson: python -m pip install meson
Open a x64 visual studio command shell
Update your path variable in this shell: set PATH=C:\gstreamer\1.0\msvc_x86_64\bin;%PATH% (note that pkg-config is included in the installation of gstreamer).
cd to your path where you cloned gst-rtsp-server
Run meson setup: meson setup build

I'm trying to compile mpfr on AIX and get an error finding TLS support. My end goal is to have a working gcc (9.3) with libstdc++ support for threads and TLS.
I tried compiling with both an existing gcc on the machine (which is 8.3 and doesn't have TLS support, as it seems) and using the built-in xlC (V12.1) on the machine.
I compiled GMP-6.2.0:
(gcc attempt): ./configure --enable-shared --enable-static CFLAGS=-fPIC CXXFLAGS=-fPIC --prefix=$OUTDIR --host=powerpc-ibm-aix7.1.0.0
(xlc attempt): ./configure --enable-shared --enable-static CC=xlc CXX=xlc CFLAGS=-qPIC CXXFLAGS=-qPIC --prefix=$OUTDIR --host=powerpc-ibm-aix7.1.0.0
gmake all
gmake check
gmake install
In both cases gmp successfully tests and installs.
Trying to configure mpfr-4.0.2 results in
(gcc attempt): ./configure --enable-shared --enable-static CFLAGS=-fPIC CXXFLAGS=-fPIC --with-gmp=$OUTDIR --prefix=$OUTDIR --host=powerpc-ibm-aix7.1.0.0
(xlc attempt): ./configure --enable-shared --enable-static CC=xlc CXX=xlc CFLAGS="-qPIC -qtls" CXXFLAGS="-qPIC -qtls" --with-gmp=$OUTDIR --prefix=$OUTDIR --host=powerpc-ibm-aix7.1.0.0
results in the following error in config.log
(gcc attempt):
configure:16567: checking for TLS support
configure:16595: gcc -o conftest -fPIC -I{OUTDIR}/include -I./src -L{OUTDIR}/lib conftest.c >&5

(xlc attempt):

ld: 0711-317 ERROR: Undefined symbol: .__tls_get_addr
I've tried a dozen different flags and configurations but mostly I don't think I'm in the correct direction - every dependency seems circular. I believe compiling with xlc is the correct idea here, but I just can't figure how to get it properly support TLS.
I also thought that I can ignore this and continue, and later compile libstdc++ again with support for TLS - but that also brought me to a dead end.
Edit:
Taking more actions on using xlc: I tried compiling the generated conftest.c (https://gist.github.com/NitzanEgozy/265e54e3353aefc79558c860b543a98f) manually:

Removing -qtls throws The '__thread' keyword is not supported on the target platform. The keyword is ignored.
AFAIK if native TLS is not available gcc emulates it using pthread keys, and i think gcc does not even support native TLS on aix. adding "-pthread" flag to the configuration will enable the appropriate threading support.
the current gcc from the ibm aixtoolbox has the appropriate default threading model enabled, hope this helps a little bit.

Is there a way to get linking running on the board?
What may be the Issue?

After much trouble I cross-compiled a fully up-to-date version of ar (i thing the one on the board was outdated) and I got rid of BusyBox.
Now everything works as I expected.
I have a Ubuntu server with Slicehost (now RackSpace) and am trying to get GNUstep installed so that I can compile Objective-c code.
After installing the world via apt-get and going through numerious blogs to try and get my source compiled, it now seems clear to me that I don't have the Foundation.h header files installed and I have no idea where to get these from.
They are present on my Mac, maybe I could simply copied them over to Ubuntu and it'll all be gravy - wishful thinking?
Any help on how to locate and install the Foundation.h files is appreciated.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:
The following packages have unmet dependencies.

Which version of Ubuntu server are you running?
I'm running Ubuntu server 10.04 LTS and found my Foundation.h under /usr/include/GNUstep/Foundation/Foundation.h, it belongs to the package libgnustep-base-dev. Might be different in other versions...
Maybe you could post your output of dpkg -l | grep -i gnustep to compare our lists.
