Hi, Please review the following fix:
http://cr.openjdk.java.net/~arajkumar/8203294/webrev Root cause: Currently C and C++ standard libraries are linked dynamically(except javafx.web), it may restrict the usage of javafx on old Linux distros when we upgrade to latest compiler(GCC 7.3?) Solution: Fix all javafx module dynamic library linking process to use '-static-libgcc -static-libstdc++' flags to force the static linking of standard libs. Additionally '-ffunction-sections -fdata-sections' GCC compiler flags[1] are used to reduce the library size due to static linking. Testing: Used the following command to see the size difference of javafx libraries with and without static linking ```` find build/modular-sdk/modules_libs/ -type f -name *.so -exec ls -lh {} \; -exec sh -c 'ls -lh $JAVA_HOME/lib/$(basename {})' \; ```` Used the following command to verify the fix, ```` find build/modular-sdk/modules_libs -name *.so -exec sh -c "readelf -d {} | egrep 'libgcc|libstdc++' > /dev/null && echo {}" \; ```` [1] https://gcc.gnu.org/onlinedocs/gnat_ugn/Compilation-options.html Thanks, Arun
