      perf tools: Fix -ldw/-lelf link test when static linking · d14c4965
      Mike Frysinger 提交于
      Since libelf sometimes uses libpthread, we have to list that after -lelf
      when someone tries to build statically.  Else things go boom:
      
      Makefile:479: *** No libelf.h/libelf found, please install \
      	libelf-dev/elfutils-libelf-devel.  Stop.
      
      Similarly, the -ldw test fails as it often uses -lz:
      
      Makefile:462: No libdw.h found or old libdw.h found or elfutils is older \
      	than 0.138, disables dwarf support. Please install new elfutils-devel/libdw-dev
      
      And if we add debugging to try-cc, we see:
      + echo '#include <dwarf.h>
      
      int main(void)
      {
              Dwarf *dbg = dwarf_begin(0, DWARF_C_READ);
              return (long)dbg;
      }'
      + i686-pc-linux-gnu-gcc -x c - -O2 -pipe -march=atom -mtune=atom -mfpmath=sse -g \
      	-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE \
      	-ldw -lelf -static -lpthread -lrt -lelf -lm -o .24368
