https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95005 Michael Kuhn changed: What|Removed |Added Attachment #48482|0 |1 is obsolete|| --- Comment #5 from Michael Kuhn --- Created attachment 48516 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48516=edit Updated zstd patch Thanks for investigating! Sadly, this still does not work for me, even with master. If I do "make lto-compress.o" in the gcc subdirectory, it works (and includes the include path), but a normal "make" in the build directory does not. In Spack, another issue has come up: When building with Clang (as frequently done on macOS), libzstd cannot be found. After some investigation, it seems that the library path is also not set correctly. I have come up with the attached updated patch that allows me build GCC with zstd in a non-standard path. It is also a bit cleaner than the previous approach.

I applied your patch on top of the GCC 10.1.0 tarball. Sadly, it still fails with the same error. It looks like ZSTD_CPPFLAGS is not actually exported/set anywhere (only available in configure), which is why I made use of ZSTD_INCLUDE.
[Bug other/95005] New: zstd.h not found if installed in non-system prefix
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95005 Bug ID: 95005 Summary: zstd.h not found if installed in non-system prefix Product: gcc Version: 10.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other Assignee: unassigned at gcc dot gnu.org Reporter: gcc at ikkoku dot de Target Milestone: --- Created attachment 48482 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48482=edit Add zstd include directory While adding GCC 10.1.0 to Spack, I ran into a problem with zstd: When specifying a non-system prefix with --with-zstd (Spack installs each package in its own prefix), the build of lto-compress.o failed because it could not find the zstd.h header. The attached patch fixes the problem. It should probably be changed to export the appropriate compiler flag from configure.ac to avoid the ifeq in the Makefile. However, I wanted to avoid touching configure.ac so we do not have to regenerate configure.
