Manually installing gpg-error-config in /usr/local/bin allows libgcrypt to configure and build.

From the information in gpg-error.pc, I think it's on macOS.
In the configure script, it tries to check/locate gpg-error-config or gpgrt-config. When gpgrt-config is available, it emulates gpg-error-config.
It seems that gpgrt-config fails in your environment, for some reasons.
Could you show us the first line of gpgrt-config? It specifies the shell interpreter (usually, #!/bin/sh).
Also, please show us how it works on your environment:
$ /usr/local/bin/gpgrt-config --libdir=/usr/local/lib gpg-error --libs$ /usr/local/bin/gpgrt-config --libdir=/usr/local/lib gpg-error --modversionIf it fails, how about following?
$ bash /usr/local/bin/gpgrt-config --libdir=/usr/local/lib gpg-error --modversionComment Actions
Yes, it is on macOS.
% /usr/local/bin/gpgrt-config --libdir=/usr/local/lib gpg-error --libs -L/usr/local/lib -lgpg-error % /usr/local/bin/gpgrt-config --libdir=/usr/local/lib gpg-error --modversion 1.46

Thank you for your quick reply.
IIUC, we should apply the fix of gpg-error.m4 rE628cb1a786bd: m4: Fix detection of gpgrt's libdir.
Comment Actions
Actually, it looks as if libgpg-error-1.46 already has that fix.
Note: I am using clang, which based on the issue in rE628cb1a786bd: m4: Fix detection of gpgrt's libdir. outputs the following:
% cc -print-search-dirs programs: =/usr/local/bin libraries: =/usr/local/lib/clang/15.0.3

Thank you for the information.
I meant the fix should go into libgcrypt/m4/gpg-error.m4 too, so that the libgcrypt's configure script (generated using gpg-error.m4) can locate /usr/local/lib/pkgconfig/gpg-error.pc.

Okay. So, I removed gpg-error-config, updated libgcrypt/m4/gpg-error.m4, and then rebuilt configure. And, gcrypt configures and builds.
Will this be in the next release of libgcrypt?

Yes. It's in rCe2c0920fd7de: build: Update gpg-error.m4. for libgcrypt 1.10 branch.
