[MPlayer-dev-eng] Building mplayer with ASAN support

[Gustavo Grieco]

Hello,

I'm trying to build the last cve snapshot (export 2015-12-18) with address sanitizer in order to test in deep the last version of mplayer. I used:

$ ./configure --extra-cflags="-fsanitize=address"

but unfortunately, this is not working:

$ make
cc -MMD -MP -Wundef -Wall -Wno-switch -Wno-parentheses -Wpointer-arith -Wredundant-decls -Werror=format-security -Wstrict-prototypes -Wmissing-prototypes -Wdisabled-optimization -Wno-pointer-sign -Wdeclaration-after-statement -std=gnu99 -Werror-implicit-function-declaration -D_POSIX_C_SOURCE=200112 -D_XOPEN_SOURCE=600 -D_ISOC99_SOURCE -I. -Iffmpeg -O4 -march=native -mtune=native -pipe -ffast-math -fomit-frame-pointer -fno-tree-vectorize -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -fsanitize=address -fpie -DPIC -D_REENTRANT -I/usr/include/p11-kit-1    -D_REENTRANT   -I/usr/include/freetype2 -DZLIB_CONST -c -o command.o command.c

If i disable the custom CFLAGS, mplayer will compile correctly. Is ASAN supported somehow?

Thanks!
