Can someone give me hint as to what I'm doing wrong here, I have a C++
package that builds fine for f35 & f36 with x86_64 & aarch64, but
which fails on f37-x86_64 (the build is ok on f37-aarch64):

This command line contains "-isystem /usr/include", on other architectures this is not included,
this is the difference. But currently I cannot figure out where this "-isystem /usr/include" came from.
So now I managed to get build successful:
https://copr.fedorainfracloud.org/coprs/mtasaka/IfcOpenShell-test/build/4812428/
Short answer:
In your IfcOpenShell.spec on %cmake line, ```-DCMAKE_CXX_FLAGS=-lxml2``` is wrong.
At least this should be changed to ```-DCMAKE_CXX_FLAGS="-lxml2 %build_cxxflags"``` or so.
( but actually "-lxml2" should not be written in CMAKE_CXX_FLAGS, because this is for
"compilation" flag, not for "linkage" option ).
Some long story trying to explain:
First of all f36 buildroot uses cmake-3.22.2, while f37 buildroot uses cmake-3.24.1, so
cmake behavior can differ between f36 and f37.
Then looking at build-live.log.gz, on aarch64:
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
, while on x86_64 (this is both f37 and f36):
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - failed
and looking at redhat-linux-build/CMakeFiles/CMakeError.log (on x86_64), it says:
====================================================================
1 Detecting CXX compiler ABI info failed to compile with the following output:

67 collect2: error: ld returned 1 exit status
====================================================================
So here on linkage "-spec=/usr/lib/rpm/redhat/redhat-hardened-ld" is specified which uses -pie, while on compilation
the "correspoinding" option (-fpie or so, which is usually passed with -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1) is not
passed, because IfcOpenShell.spec says "-DCMAKE_CXX_FLAGS=-lxml2" which overrides Fedora %build_cxxflags ,
and on x86_64 this causes relocation error (on aarch64 it seems to not cause error, by chance?).
When changing to ```-DCMAKE_CXX_FLAGS="-lxml2 %build_cxxflags"```, this succeeds and then

====================================================================
So on successful "Detecting CXX compiler ABI info", cmake detects "implicit include directories".
And, from here this is my **guess**, that when cmake fails to detect implicit include directories,
cmake on f37 seems to add "-isystem /usr/include", perhaps.
P.S.
Changing to ```-DCMAKE_CXX_FLAGS="-lxml2 %build_cxxflags"``` makes total build time much longer -
perhaps because of -flto and -g . Now aarch64 build time gets 10 hours - as copr default timeout is
5 hours, you have to specify timeout option explicitly.

Mamoru
