I have, a couple of time, successfully built git for AIX. However, my
prior attempt (version 2.18) - I never got around to finishing and today
with version 2.23.0 - I am unsure how to proceed without a lot of hacking.
Just some comments - long long way from calling anything a bug - just
not as portable as I would have hoped.
The simple issues:
1. The "Makefile" is surprising. I expect to run ./configure (or better,
out-of tree, e.g., ../src/git-2.23.0/configure). Just running OOT
configure does not result in a "Makefile". So, copy source tree to dest
and try again.
2. Makefile assumes gmake. Standard make does not support :: syntax
(fix: install cmake)
3. The default CFLAGS contains -Wall. Not all compilers support -Wall.
"Fixed" by adding CFLAGS="-g -O2". I am also undecided on having -g as a
default flag.
4. Must have gettext installed, which needs GNU libiconv - sad to have
these libraries as additional dependencies. e.g., bash 4.4 finally
removed the gettext and iconv gnu dependencies. -- FYI!
5. Another "gcc"? dependency: "git-compat-util.h", line 361.1: 1506-277
(S) Syntax error: possible missing ';'
FIX: add 'CC=xlc_r' to get language extensions
6. Needs curl (libcurl and curl.h), but does not check until much later:
FIX install curl; FIX2 add -I flag to find $prefix/include to CFLAGS
(.e.g., CFLAGS="-g -O2 -I/opt/include") - FYI GNU autotools also fail to
include $prefix/include
7. More stuck here. libssh2 is built by curl, but as a static library. I
could "hack" the libssh2.o file into the linkage, but unclear how well
that will work. Also wonder if libssh2 is "required" or optional. For
curl it has been optional (and I think it still is).
Current status:

This will need, at the least an additional LDFLAGS added to the make
command ('LDFLAGS="-L/opt/lib"'), but I still have to find where the
-lssh2 is generated.
Not sure - if I can help - but do hope this already helps in a (small) way.

Michael
