Recommended is no build dependency (g++ is build-essential), and since the upstream build uses gcc/g++ on Linux by default it is already fine for that. > Emmanuel Bourg cu Adrian -- "Is there not promise of rain?"

Thank you very much for the patch Adrian, I confirm it works. I'll upload a new version soon. What is the recommended way to depend on GCC? Should the package depend on g++ (>= 4:6), or should it depend on gcc-6 with a build adjusted to use it? Emmanuel Bourg
Bug#831153: Fix for the openjdk-8-jre-dcevm FTBFS
Control: tags -1 -help Control: tags -1 +patch There are 5 different issues regarding this FTBFS and attempts to resolve it: 1. Changing the build dependencies doesn't change the compiler. Adding g++-5 resulted in #835956, but when you don't tell the build system of the software to use this compiler the default g++ is still used. This explains why that build dependency didn't help (but point 2 is a better solution). 2. --std=gnu++98 fixes the C++ related build failure. 3. readdir_r() is deprecated in latest glibc. This generates a new warning, and openjdk-8-jre-dcevm turns all warnings into errors by passing -Werror to the compiler. 4. Upstream uses CFLAGS instead of CXXFLAGS for C++ This is a bug somewhere in the upstream code, using DEB_CXXFLAGS_MAINT_APPEND didn't work. 5. I didn't encounter the original build failure due to missing jvmti.h It seems the file from openjdk-8-jdk-headless was found successfully? The following change gave me a successful build: --- debian/rules.old2016-10-17 15:48:31.0 + +++ debian/rules2016-10-17 15:49:00.0 + @@ -1,5 +1,7 @@ #!/usr/bin/make -f +export DEB_CFLAGS_MAINT_APPEND = -std=gnu++98 -Wno-error=deprecated-declarations + PACKAGE = $(shell dpkg-parsechangelog -S Source) export DISABLE_HOTSPOT_OS_VERSION_CHECK=ok cu Adrian -- "Is there not promise of rain?"
