Bug ID: 505233
Summary: Build rules in memcheck apply CFLAGS after
customizations made by configure, leading to unwanted
configuration or errors
Classification: Developer tools
Product: valgrind
Version First 3.25 GIT
Reported In:
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: memcheck
Assignee: jsew...@acm.org
Reporter: jk...@apache.org
Target Milestone: ---
In an environment where CFLAGS is set by default to include
`-fstack-protector-strong`, a build of Valgrind 3.25.1 will fail because the
memcheck configure-generated build places $(CFLAGS) after
$(memcheck_amd64_linux_CFLAGS), causing stack protector to be enabled; for
example this excerpt from the generated Makefile in memcheck:
```
memcheck_amd64_linux-mc_main_asm.obj: mc_main_asm.c
$(AM_V_CC)$(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES)
$(memcheck_amd64_linux_CPPFLAGS) $(CPPFLAGS) $(memcheck_amd64_linux_CFLAGS)
$(CFLAGS) -MT memcheck_amd64_linux-mc_main_asm.obj -MD -MP -MF
$(DEPDIR)/memcheck_amd64_linux-mc_main_asm.Tpo -c -o
memcheck_amd64_linux-mc_main_asm.obj `if test -f 'mc_main_asm.c'; then
$(CYGPATH_W) 'mc_main_asm.c'; else $(CYGPATH_W) '$(srcdir)/mc_main_asm.c'; fi`
$(AM_V_at)$(am__mv) $(DEPDIR)/memcheck_amd64_linux-mc_main_asm.Tpo
$(DEPDIR)/memcheck_amd64_linux-mc_main_asm.Po
```
