Source: blt
Version: 2.5.3+dfsg-8
Tags: ftbfs patch upstream
Hello,
I noticed that blt fails to build from source when the CC variable is
exported. It does not matter what you export it to. It can be "cc",
"gcc" or "x86_64-linux-gnu-gcc" or even "false" or "true". The behavior
is always the same: It discovers a compiler and then fails to find any
header. With the help of Timo Roehling and Tobias Frost, I discovered
that the root cause for the problem resides in configure.in. The
AC_PROG_CC macro is conditionalized. When passing --with-cc, exporting
CC or setting the blt_cv_prog_cc cache variable, AC_PROG_CC is skipped
over. Doing so breaks all sorts of other checks. Instead, we should set
CC to whatever we prefer and then always run AC_PROG_CC. Then blt no
longer FTBFS. Please consider applying the attached patch and forwarding
it upstream.
Helmut
