Hi, gpgme-1.18.0 dropped a bunch of internal symbols, including progress_callback (see e.g. callbacks.h which has a comment at the top saying it's internal). Unfortunately, this is what LibreOffice uses to detect [0] gpgme: ``` # progress_callback is the only func with plain C linkage # checking for it also filters out older, KDE-dependent libgpgmepp versions AC_CHECK_LIB(gpgmepp, progress_callback, [ GPGMEPP_LIBS=-lgpgmepp ], [AC_MSG_ERROR(gpgmepp not found or not functional)], []) ``` Originally reported downstream in Gentoo at https://bugs.gentoo.org/865321. As a result, LibreOffice fails to build with newer gpgme: ``` checking for gpgme++/gpgmepp_version.h... yes checking for progress_callback in -lgpgmepp... no configure: error: gpgmepp not found or not functional ``` And from config.log: ``` configure:40830: checking for progress_callback in -lgpgmepp configure:40853: x86_64-pc-linux-gnu-gcc -o conftest -pipe -march=native -fno-diagnostics-color -O2 -I/usr/include/python3.10 -Wl,-O1 -Wl,--as-needed -Wl,--defsym=__gentoo_check_ldflags__=0 conftest.c -lgpgmepp >&5 /usr/lib/gcc/x86_64-pc-linux-gnu/12.1.1/../../../../x86_64-pc-linux-gnu/bin/ld: /var/tmp/portage/app-office/libreoffice-7.3.5.2/temp/ccH6cG0Y.o: in function `main': conftest.c:(.text.startup+0x7): undefined reference to `progress_callback' collect2: error: ld returned 1 exit status configure:40853: $? = 1 ``` [0] https://github.com/LibreOffice/core/blob/master/configure.ac#L12566 Best, sam
