Package: src:plplot Version: 5.9.9-2 Severity: normal -fvisibility=hidden set in debian/rules breaks gnudatalanguage bindings. it removes the plP_w3wc? functions from plcvt.c:
CFLAGS = $(shell dpkg-buildflags --get CFLAGS) CFLAGS += -fvisibility=hidden nm ./debian/build_tmp/src/libplplotd.so | grep w3wc gives this result when not build with =hidden 000000000001d000 T plP_gw3wc 0000000000023410 T plP_w3wcx 0000000000023440 T plP_w3wcy 0000000000023490 T plP_w3wcz and only this if built with =hidden. 000000000001d000 T plP_gw3w debian is "lucky" in that sense that the CFLAGS are not exported to the build, so the symbols are there and gnudatalanguage builds. See the buildlogs. In Ubuntu the flag is added and gnudatalanguage breaks. Not sure if this is a bug in the packaging, debian or ubuntu. please reassign the bug to gnudatalanguage is the symbols are meant to be hidden and gnudatalanguage should not using them.
