Hello everyone! I'm having trouble compilig git source since version 2.50 ,  for RHEL 6 (both in redhat 6-6 and 6.10).
the same source  compiles fine in  RHEL8 (Red Hat Enterprise Linux release 8.10 (Ootpa))
first compiler complans about missing random.h in compat/posix.h ,if you copy missing random.h file to RHEL6 machine to the /usr/include/sys directory  then errors change to  whole bunch of other errors like  
error: expected declaration specifiers or ‘...’ before numeric constant
 
   45 | #define toupper(x) sane_case((unsigned char)(x), 0)
both working and non working systems have same gcc 13-4.0 . Last version that compiles  in both rhel 6 and rhel 8 is 2.49.1 Any ideas ?

Re: git 2.50 and 2.50.1 src fails to compile in rhel 6

I/m soorry for the noob quesion but how do I get the patched version of the sane-ctype.h? I/m not sure where exactly to apply the patch to. I only see the diff, and not the whole file itself. And what are the chances of this patch being merged to master branch

Wow, RHEL6! I think the oldest version we support is RHEL8.

[Moving header files from a newer glibc to RHEL6 is a definite no-no - don't do that!]

Here, your glibc version is too old for getrandom(), so you need to build with CSPRNG_METHOD= set either in your config.mak or on the make invocation, something like:

    make CSPRNG_METHOD=

this would probably not work, because of the overrides in config.mak.uname and config.mak.autogen, so config.mak is better:

$ make clean $ echo "CSPRNG_METHOD=" > config.make $ make
