Hello;
I am compiling on

I have a problem with AC_CHECK_TARGET_TOOL setting the standard environment variables
It finds the system version tools like ar instead of x86_64-ar and notes them, it finds '/usr/bin/ar" but then
doesn't set AR properly.
In the configure.ac I have a section looking for tools with target canonical names
AC_CHECK_TARGET_TOOL([CPP], cpp [], [])
AC_CHECK_TARGET_TOOL([CC], gcc, [], [])
AC_CHECK_TARGET_TOOL([CXX], g++, [], [])
AC_CHECK_TARGET_TOOL([RANLIB], ranlib, [], [])
AC_CHECK_TARGET_TOOL([LD], ld, [], [])
AC_CHECK_TARGET_TOOL([AR], ar, [], [])
AC_CHECK_TARGET_TOOL([AS], as, [], [])
AC_CHECK_TARGET_TOOL([READELF], readelf, [], [])
AC_CHECK_TARGET_TOOL([OBJDUMP], objdump, [], [])
AC_CHECK_TARGET_TOOL([OBJCOPY], objcopy, [], [])
AC_CHECK_TARGET_TOOL([SIZE], size, [], [])
AC_CHECK_TARGET_TOOL([NM], nm, [], [])
AC_CHECK_TARGET_TOOL([STRIP], strip, [], [])
AC_SUBST(CPP)
AC_SUBST(CC)
AC_SUBST(CXX)
AC_SUBST(RANLIB)
AC_SUBST(LD)
AC_SUBST(AR)
AC_SUBST(AS)
AC_SUBST(READELF)
AC_SUBST(OBJDUMP)
AC_SUBST(OBJCOPY)
AC_SUBST(SIZE)
AC_SUBST(NM)
AC_SUBST(STRIP)
And then when configure is finished, the config.log has some sort of intermediate values instead of the final environment values
like AR='ac_ct_AR' which then crashes when I try and use AR. Why is configure not putting the target variables into the common environment variables?
For example
CPP='ac_ct_CPP'
CXX='ac_ct_CXX'
And yet CC is set properly
CC='gcc'
Here is an excerpt from config.log:
