Lib Boost Issues on OSX

[Brad Olson]

ERNE is 1.4.4 is failing to compile on my OSX systems.

Lib Boost is installed, but it is having problems finding boost.filesystem even though it is installed.

I tried installing boost both with brew and with MacPorts. This problem occurs on both OSX10.6 and OSX10.7 all with current versions of Xcode.

Below is the boost part of ./configure from a 10.7 system

===== BOOST support (required) =====
checking for Boost headers version >= 1.40.0... yes
checking for Boost's header version... 1_55
checking for the toolset name used by Boost for g++... xgcc42 -xgcc
checking boost/system/error_code.hpp usability... yes
checking boost/system/error_code.hpp presence... yes
checking for boost/system/error_code.hpp... yes
checking for the Boost system library... yes
checking boost/filesystem/path.hpp usability... yes
checking boost/filesystem/path.hpp presence... yes
checking for boost/filesystem/path.hpp... yes
checking for the Boost filesystem library... no
configure: error: cannot find the flags to link with Boost filesystem

Here is the same from a 10.6 system

===== BOOST support (required) =====
checking for Boost headers version >= 1.40.0... /opt/local/include
checking for Boost's header version... 1_55
checking for the toolset name used by Boost for g++... xgcc42 -xgcc
checking boost/system/error_code.hpp usability... yes
checking boost/system/error_code.hpp presence... yes
checking for boost/system/error_code.hpp... yes
checking for the Boost system library... yes
checking boost/filesystem/path.hpp usability... yes
checking boost/filesystem/path.hpp presence... yes
checking for boost/filesystem/path.hpp... yes
checking for the Boost filesystem library... no
configure: error: cannot find the flags to link with Boost filesystem

I have recently compile other sources against boost (not ERNE) and not had issues.

Dear Brad,
the problem arise in the procedure (not wrote by me) for the autodection of the BOOST parameters (for details, see: https://github.com/tsuna/boost.m4/issues/19). I updated the code and tested successfully into this branch:
https://sourceforge.net/p/erne/code/HEAD/tree/branches/1.4.4-1-osx-issue/

Can you download and compile (there is a "Download snapshot" link) this version and confirm if it works for you?

Best,
Cristian

I found this issue through Google. The linked file helped me to get past the ./configure step, however I can not get the it to make now. I get the following error: In file included from data_structures/Hash.cpp:26:
data_structures/Hash.h:139:2: error: reference to 'mutex' is ambiguous

/usr/local/include/boost/thread/pthread/mutex.hpp:91:11: note: candidate found

Am I doing something incorrectly? Thanks,
Nat

[Cristian Del Fabbro]

Dear Nat, could you try modifing the 139th line of src/data_structures/Hash.h
from:
mutex dummyMutex;
to:
boost::mutex dummyMutex;

and return a feedback to me? (I suppose that you will obtain a similar error but in another file)

Thanks,
Cristian

The new error output:

data_structures/Hash.cpp:75:13: error: no viable overloaded '='
dummyMutex = NULL;
~~~~~~~~~~ ^ ~~~~
/usr/local/include/boost/thread/pthread/mutex.hpp:96:9: note: candidate function

Dear Nat, try to modify the line
dummyMutex = NULL;
with
dummyMutex = (boost::mutex *)NULL;

Best,
