MesaLib-9.1.3 Configure error

Dinesh Raja · 06-30-2013, 10:10 AM

Hello,I am doing BLFS(Ongoing Development) i used the following code to compile MesaLib

Code:

patch -Np1 -i ../MesaLib-9.1.3-llvm_fixes-1.patch &&
autoreconf -fi &&
./configure CFLAGS="-O2" CXXFLAGS="-O2"    \
            --prefix=/usr                  \
            --sysconfdir=/etc              \
            --enable-texture-float         \
            --enable-gles1                 \
            --enable-gles2                 \
            --enable-openvg                \
            --enable-osmesa                \
            --enable-xa                    \
            --enable-gbm                   \
            --enable-gallium-egl           \
            --enable-gallium-gbm           \
            --enable-glx-tls               \
            --with-llvm-shared-libs        \
            --with-egl-platforms="drm,x11" \
            --with-gallium-drivers="nouveau,r300,r600,radeonsi,svga,swrast" &&
make

I am getting the following error

Code:

configure: error: LLVM R600 Target not enabled.  You can enable it when building the LLVM
                      sources with the --enable-experimental-targets=R600
                      configure flag

Additional Info:
I have compiled and installed LLVM 3.2 with the following command sequence

Code:

sed -e 's:\$(PROJ_prefix)/docs/llvm:$(PROJ_prefix)/share/doc/llvm-3.2:' \
    -i Makefile.config.in &&
CC=gcc CXX=g++                         \
./configure --prefix=/usr              \
            --sysconfdir=/etc          \
            --enable-libffi            \
            --enable-optimized         \
            --enable-shared            \
            --enable-targets=all       \
            --disable-assertions       \
            --disable-debug-runtime    \
            --disable-expensive-checks &&
            
make

Here i have removed "--enable-experimental-targets=R600" since i got errors with this unrelavant target like that but this has screwed up my Mesalib compilation

Some please help me to overcome this issue.

What graphic card do you have?
Do you need that experimental driver?
Otherwise you can just remove it from the configure line. I have Intel and I only used
--with-gallium-drivers="i915".

I would have thought that as you have removed the R600 option from llvm you should remove it from the list of drivers for mesalib.

I tried compilation after removing R600 but again the same error

I tried configuring Mesalib with the following code but still the same error

Code:

patch -Np1 -i ../MesaLib-9.1.3-llvm_fixes-1.patch &&
autoreconf -fi &&
./configure CFLAGS="-O2" CXXFLAGS="-O2"    \
            --prefix=/usr                  \
            --sysconfdir=/etc              \
            --enable-texture-float         \
            --enable-gles1                 \
            --enable-gles2                 \
            --enable-openvg                \
            --enable-osmesa                \
            --enable-xa                    \
            --enable-gbm                   \
            --enable-gallium-egl           \
            --enable-gallium-gbm           \
            --enable-glx-tls               \
            --with-llvm-shared-libs        \
            --with-egl-platforms="drm,x11" \
            --with-gallium-drivers="nouveau,r300,radeonsi,svga,swrast,i915" &&
make

My result is

Code:

configure: error: LLVM R600 Target not enabled.  You can enable it when building the LLVM
                      sources with the --enable-experimental-targets=R600
                      configure flag

My problem is enabling experimental-targets=R600 is also generating errors

please help me to fix this loop error

You didn't answer what graphic card you have. You're trying to compile the drivers for nvidia(nouveau), ati(radeon) and now also intel(i915) card. Remove everything you don't need.

from blfs about llvm:

Quote:

--enable-experimental-targets=R600: This switch enables R600 target which is required by Mesa to build the radeonsi 3D driver. It can be used for R600 LLVM backend and OpenCL state tracker in Mesa.

from blfs about mesalib:

Quote:

You will need to remove r300, r600 and radeonsi from the list if you did not install LLVM-3.3.

In other words, you need to also remove r300 and radeonsi, or build R600.

Keith Hedger · 06-30-2013, 01:05 PM

Do you NEED LLVM I compiled mesalib without it just fine, but I use the ati propriety driver anyway.

I am sorry i missed that i am using Intel Graphics card and i removed r300 and radeonsi, or build R600 now i am able to compile it but my question is last time <My Previous BLFS build> LLVM,Mesalib compiled without errors i dont know what has caused this

anyway thanks for the solution marking this as solved.

I too skipped LLVM now Mesalib is working good thank you Keith Hedger.
