Pluto MPI build fail when configuring pet about pluto

[georgebisbas]

Hi Uday,

I managed to surpass the issue with FileCheck but now my new issue seems related to this one.
I could not find a solution based on the comments above.
Any help?

Attached you may find my config.log file
config.log

Thank you in advance,
George

False alarm.
I found out that I needed to do
sudo apt install libclang-dev
I thought I have done it before.

Thanks,

It will only work with 3.4. Could you attach your config.log (or paste the relevant lines) when you obtain the error with clang 3.4? Thanks.

when I try
./configure
these are the last lines of the output

checking dynamic linker characteristics... (cached) GNU/Linux ld.so
checking how to hardcode library paths into programs... immediate
checking for a sed that does not truncate output... (cached) /bin/sed
checking which clang to use... system
checking for llvm-config... no
configure: error: llvm-config not found
checking for pet/Makefile... no
configure: error: configure in pet/ failed

It doesn't find the clang even though it's installed and it's the 3.4 version.

I tried with a llvm3.4, which i built locally
./configure --with-clang-prefix=/path_to_llvm3.4/build/
i get this :

checking dynamic linker characteristics... (cached) GNU/Linux ld.so
checking how to hardcode library paths into programs... immediate
checking for a sed that does not truncate output... (cached) /bin/sed
checking which clang to use... system
checking for llvm-config... no
checking for main in -lLLVM-3.4svn... no
checking clang/Basic/SourceLocation.h usability... no
checking clang/Basic/SourceLocation.h presence... no
checking for clang/Basic/SourceLocation.h... no
configure: error: clang header file not found
checking for pet/Makefile... no
configure: error: configure in pet/ failed

I hope that this explains the problem, which is that llvm-config and clang aren't being detected.

I actually meant the config.log in the pet directory. Could you paste the relevant lines from pet/config.log. That'll say exactly where exactly it was looking - it's of course clear it can't find it. Also, please don't use the SVN version, but instead the stable release. Do you have an llvm-config in your llvm build/bin?

[ThinhinaneIhadadene]

Sorry, I didn't understand.
Here is the file :
config.log

It looks like you don't have the right libraries at the right place. From your config.log, it's looking for libLLVM-3.4svn.* in /home/tina/pfe/llvm-3.4/build/lib/.

configure:15638: gcc -o conftest -g -O2 -L/home/tina/pfe/llvm-3.4/build/lib -lrt -ldl -lpthread -lz conftest.c -lLLVM-3.4svn >&5
/usr/bin/ld: cannot find -lLLVM-3.4svn
collect2: error: ld returned 1 exit status
configure:15638: $? = 1
configure: failed program was:

What are the contents /home/tina/pfe/llvm-3.4/build/lib/? Could you also let me know the output when you run:
$ /home/tina/pfe/llvm-3.4/build/bin/llvm-config --version --cxxflags

You could just try with the stable 3.4 version from llvm.org - it will work.

[ThinhinaneIhadadene]

The contents of /home/tina/pfe/llvm-3.4/build/lib/ :
content.txt
The results of
./home/tina/pfe/llvm-3.4/build/bin/llvm-config --version --cxxflags
is
-I/home/tina/pfe/llvm-3.4/include -I/home/tina/pfe/llvm-3.4/build/include -fPIC -fvisibility-inlines-hidden -Wall -W -Wno-unused-parameter -Wwrite-strings -Wno-missing-field-initializers -pedantic -Wno-long-long -Wno-maybe-uninitialized -Wnon-virtual-dtor -O3 -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS
I've tried with a stable version I get the same result.

[bondhugula]

It's looking for the wrong library name suffix - you don't have anything libLLVM3.4svn* in your lib.

I've tried with a stable version I get the same result.

With the stable version, it's obviously not going to look for 3.4svn; so, you can't get the same result unless you did something wrong. (By the 3.4 stable version, I meant building from the sources here: http://releases.llvm.org/download.html#3.4
http://releases.llvm.org/3.4/clang-3.4.src.tar.gz, http://releases.llvm.org/3.4/llvm-3.4.src.tar.gz)
