libgcrypt 1.9.0 fails to build with LTO #689

Open automorphism88 opened 3 years ago

automorphism88 commented 3 years ago

I tried to build the libgcrypt 1.9.0 upgrade just now and got this error:

Disabling LTO allowed the build to complete successfully, but I haven't tried all possible combinations of flags to see if there might be a way to make LTO work with different flags. However, I did try disabling ccache, and that didn't help. Output of emerge --info is below:

I encountered the same error, and adding -ffat-lto-objects lets it build again.

Add this in your env:

gcry_cv_gcc_arm_platform_as_ok=no
gcry_cv_gcc_aarch64_platform_as_ok=no

or disable other platforms via EXTRA_ECONF (see ./configure --help).

alanswanson commented 3 years ago

Trying fat-lto-objects failed in configures C compilation test - usual occurrence with fat-lto-objects for a 32/64 multilib build. However applying the following upstream commit (needed to remove the last four hunks for s390 for the ebuild) fixes the LTO build.

khuei commented 3 years ago

Are you still having the same issue?

I don't seem to encounter with this issue on libgcrypt-1.9.2

alanswanson commented 3 years ago

All fine since the libgcrypt release with previously referenced commit.
