curl 7.79 does not compile on linux and mac with debug flags

[tawmoto]

I am trying to build curl as I do it for years, with the same flags.

FLAGS=" -Wa,-compress-debug-sections=none -fPIC -DPIC -m64" LDFLAGS=" -Wl,-compress-debug-sections=none" ./configure --enable-ftp --enable-proxy --enable-ipv6 --enable-http --enable-nonblocking --enable-crypto-auth --enable-hidden-symbols --enable-soname-bump --enable-static --disable-shared --disable-dict --disable-ares --disable-telnet --disable-tftp --disable-manual --disable-rtsp --disable-file --disable-pop3 --disable-imap --disable-smtp --disable-ldap --disable-ldaps --disable-sspi --without-libssh2 --without-zlib --without-gnutls --without-nss --without-libidn --without-libidn2 --without-nghttp2 --without-librtmp --without-brotli --without-libpsl --prefix="some_install_dir" --with-ssl="ssl_dir" --disable-rt --disable-threaded-resolver --enable-debug --enable-curldebug

I get this error

The problem seems this line:
2f0bb86#r56567123

Problem is reproducible on Linux and MacOS with curl 7.79.0

Thanks

@bagder thank you very much for the fix, but I tried to implement it on my local machine and I still get the error. (i mean this change: 73b55e4)
Maybe I should change something in my building flags? I am using them for years without any problem.
Btw, the error occurs only I use --enable-debug flag.

Thank you

So what exactly did you do to "implement it" ?

Downloaded 7.79.0, unpacked it, did that change (by adding .checksrc string in the lib/Makefile.am file, like in your PR), ran configure (like in my original post) and make install.

You want to put a file in the lib/ directory and call that file .checksrc and it should have the contents shown here: https://github.com/curl/curl/blob/master/lib/.checksrc

The fix I did makes sure to include that file in release tarballs.

Thanks a lot for the solution, it works!
I guess 7.79.1 won't be released too soon with this fix, so I will create a patch on my side.

Cheers and thanks again!

7.79.1 will ship on Sep 22
