I had the need for setting additional C/C++ compilation flags in my OpenJDK8 build.
It seems they are used for most jdk C/C++ compilation, but at least the generators from
jdk/makefiles/gensrc/GensrcMisc.gmk
seem to be an exception.
Example :
configure --with-extra-cflags=-DTESTMYEXTRAFLAGC --with-extra-cxxflags=-DTESTMYEXTRAFLAGCXX
does not lead to the expected flags in the build for genSocketOptionRegistry.c :
...
/usr/local/bin/gcc -DTHIS_FILE='"genSocketOptionRegistry.c"' -c -MMD -MF /mydir/open_jdk/jdk8/linuxx86_64_opt/jdk/gensrc/genSocketOptionRegistry/genSocketOptionRegistry.d
-o /mydir/open_jdk/jdk8/linuxx86_64_opt/jdk/gensrc/genSocketOptionRegistry/genSocketOptionRegistry.o /mydir/open_jdk/jdk8/openjdk8/jdk/src/share/native/sun/nio/ch/genSocketOptionRegistry.c
...
(while the flags show up for "normal" C/C++ files .)
Is there another option (available / planned?) to configure the extra C/C++ compile flags for this special case ?
Thanks,
Matthias
