[package] libpq/15.4: MinGW undefined references when using libpq #25282

Open scandyna opened 2 months ago

scandyna commented 2 months ago

Description

While building qt/6.7.1 on Windows with MinGW gcc 13, there are a lot of undefined references, like:

C:/MinGW/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: qtbase/src/plugins/sqldrivers/psql/CMakeFiles/QPSQLDriverPlugin.dir/qsql_psql.cpp.obj: in function `QPSQLResult::isNull(int)':
C:/.conan/6faa1d/1/src/qtbase/src/plugins/sqldrivers/psql/qsql_psql.cpp:675: undefined reference to `PQgetisnull'

An example of a failing build of Qt6 is available here: https://gitlab.com/scandyna/conan-qt-builds/-/jobs/7827688162/viewer

The problem is also reproducible with the test_package provided in the libpq recipe. An example of a failing conan test is available here: https://gitlab.com/scandyna/conan-center-index-partialbasicci-sandbox/-/jobs/7833187239

I could not paste all the logs. Here is a file with all: build_test_libpq_mingw13_logs.txt

They come from this build job: https://gitlab.com/scandyna/conan-center-index-partialbasicci-sandbox/-/jobs/7833639498

I looked in a created package, and seen that libpq.a is an empty file. Also looked what patches/15/001-mingw-build-static-libraries.patch does, and found something missing. I'm testing an update on my side, and will submit a PR if ok.
