OS X 10.11.5: configure failed for isl; clang header file not found

[woll...@gmail.com]

Hi,

I am trying to install ppcg-0.06 (downloaded from http://ppcg.gforge.inria.fr). If I run ./configure I get the following output:

checking clang/Basic/SourceLocation.h usability... no

checking clang/Basic/SourceLocation.h presence... yes

configure: WARNING: clang/Basic/SourceLocation.h: present but cannot be compiled

configure: WARNING: clang/Basic/SourceLocation.h:     check for missing prerequisite headers?

configure: WARNING: clang/Basic/SourceLocation.h: see the Autoconf documentation

configure: WARNING: clang/Basic/SourceLocation.h:     section "Present But Cannot Be Compiled"

configure: WARNING: clang/Basic/SourceLocation.h: proceeding with the compiler's result

configure: WARNING:     ## ----------------------------------------------- ##

configure: WARNING:     ## Report this to isl-dev...@googlegroups.com ##

configure: WARNING:     ## ----------------------------------------------- ##

checking for clang/Basic/SourceLocation.h... no

configure: error: clang header file not found

configure: error: ./configure failed for isl

I think the problem is that the configure uses the system default clang of OS X, but I have another version of clang (clang-3.8) installed on my system. How can I tell configure to use a different clang version?

Thanks in advance. I attached the config.log file.

Use --with-clang-prefix (see README).

--with-clang-prefix does not change anything. I still get the same error message.

[Alexandre Isoard]

As an alternative solution, I regularly compile those tools on OS X against a custom llvm/clang tool chain but I use environment variables:

Add '/path/to/llvm/bin' to PATH
Add '/path/to/llvm/lib' to {DYLD_,LD_,}LIBRARY_PATH
Add '/path/to/llvm/include' to CPATH

Where '/path/to/llvm/' is the directory in which you installed your custom llvm (prefix at llvm/clang configuration).

You sent PPCG's config.log, while the error occurs while configuring isl.
Pleas send isl/config.log.

I added the missing log file, sorry.

Unfortunately, this does not help.

It seems your g++ cannot parse the clang headers (at least not with
the options that were used when compiling clang).
Try compiling ppcg with the same compiler that was used to compile clang
(probably clang).

Is there an easy way to change that in the configure script?

The compiler to use can be set using the CC environment variable. Use

./configure CC=clang

I installed the latest version of llvm and clang from the git repository and run configure for ppcg again with:

./configure CC=clang-3.9 --with-clang-prefix=/Users/c-Mac/Applications/llvm/install/llvm

My llvm and clang is installed in /Users/c-Mac/Applications/llvm/install/llvm

I configured the PATH, {DYLD,LD}_LIBRARY_PATH, and CPATH variables for my environment. I added the current config.log.

It fails again with:

Sorry for having forgotten to mention this:

The file in question is C++, i.e. set the C++ compiler (or both):

./configure CC=clang-3.9 CXX=clang++-3.9

Thats's it! Thank you very much!

./configure CC=clang CXX=clang++

did the job!

So ./configure is working now on my system, but the make call fails with:

  CCLD     isl_test_int

Which version of the clang libraries are you compiling against?

skimo

[Michael Kruse]

Hi,

ISL not support pre-release versions of clang.
CompilerInvocation::setLangDefaults introduced a fourth parameter
which did not exist in clang 3.8. Sven will probably add support for
it once clang-3.9 is released. Until then, please use clang-3.8 (or
earlier).

Hey,

thanks for the advice. I worked with llvm-3.9 and a switch to llvm-3.8 resolved my problem. Everything is working now.

Thanks for your help.
