Strange. `dpkg-buildpackage` really aborted with this error. Doing
`aptitude install llvm` which also installed the following packages
[INSTALLIEREN, ABHÄNGIGKEITEN] llvm-3.1:i386
[INSTALLIEREN, ABHÄNGIGKEITEN] llvm-3.1-dev:i386
[INSTALLIEREN, ABHÄNGIGKEITEN] llvm-3.1-runtime:i386
[INSTALLIEREN, ABHÄNGIGKEITEN] llvm-runtime:i386
and executing `dpkg-buildpackage again solved this issue for me.
Looking at the definition of `MESA_LLVM` it checks for `llvm-config`
if test "x$enable_gallium_llvm" = xyes; then
AC_PATH_PROG([LLVM_CONFIG], [llvm-config], [no])
if test "x$LLVM_CONFIG" != xno; then
LLVM_VERSION=`$LLVM_CONFIG --version | sed 's/svn.*//g'`
LLVM_CFLAGS=`$LLVM_CONFIG --cppflags|sed -e 's/-DNDEBUG\>//g'
-e 's/-pedantic//g'`
LLVM_LIBS="`$LLVM_CONFIG --libs`"
LLVM_LDFLAGS=`$LLVM_CONFIG --ldflags`
DEFINES="$DEFINES -D__STDC_CONSTANT_MACROS"
MESA_LLVM=1
else
MESA_LLVM=0
fi
else
MESA_LLVM=0
fi
which is only in package `llvm-3.1`.
$ dpkg -S llvm-config
llvm-3.1: /usr/lib/llvm-3.1/bin/llvm-config
llvm-3.1-dev: /usr/lib/llvm-3.1/include/llvm/Config/llvm-config.h
llvm-2.9: /usr/bin/llvm-config-2.9
llvm-2.9-dev: /usr/lib/llvm-2.9/include/llvm/Config/llvm-config.h
llvm-3.1: /usr/share/man/man1/llvm-config-3.1.1.gz
llvm: /usr/share/man/man1/llvm-config.1.gz
llvm-3.1: /usr/bin/llvm-config-3.1
llvm-2.9: /usr/lib/llvm-2.9/bin/llvm-config
llvm: /usr/bin/llvm-config
llvm-2.9: /usr/share/man/man1/llvm-config-2.9.1.gz
In llvm-2.9 it is named llvm-config-2.9.1 and therefore is not picked up
I guess.
$ ls -l /usr/bin/llvm-config
lrwxrwxrwx 1 root root 31 Jun 22 00:25 /usr/bin/llvm-config ->
../lib/llvm-3.1/bin/llvm-config
$ ls -l /usr/lib/llvm-3.1/bin/llvm-config
-rwxr-xr-x 1 root root 237356 Mai 21 14:14
/usr/lib/llvm-3.1/bin/llvm-config
But being a symlink it should have pointed to the 2.9 version before the
installation.
$ ls -l /usr/lib/llvm-2.9/bin/llvm-config
-rwxr-xr-x 1 root root 24058 Mai 20 16:39
/usr/lib/llvm-2.9/bin/llvm-config
So I am not sure what went wrong here. One idea might be, that to get
these symlinks is to have `llvm` installed.
$ dpkg -L llvm
