Compiling the boost C++ library on AIX 7.1 using xlC 13.1.2 -

i trying compile regex part of boost c++ library on aix using xlc compiler , use 64-bit dynamic library, because need compare performance of several c++ regex libraries , built-in solutions, , boost seemed viable candidate.

here exact os , compiler versions:

$ uname -a aix host_name 1 7 00f9a2144c00 $ xlc -qversion ibm xl c/c++ aix, v13.1.2 (5725-c72, 5765-j07) version: 13.01.0002.0000 

since not have root priviliges, cannot install boost library, trying compile regex part shared object file , obtain of needed headers test application. have tried compile latest available version (1.59.0), , version 1.55.0, because found ibm has released source code patch boost:

http://www-01.ibm.com/support/docview.wss?uid=swg27042921

i compile boost , copy headers , shared object file development folder using following commands:

bootstrap.sh --with-toolset=vacpp --prefix=/my/user/directory --exec-prefix=/my/user/directory ./b2 address-model=64 cxxflags=-q64 cflags=-q64 b2 tools/bcp ./dist/bin/bcp boost/regex.hpp /my/include/directory cp stage/lib/libboost_regex.so /my/library/directory 

i know add --with-libraries=regex flag compile regex part, irrelevant problems.

with both versions, or without patching boost source code, encounter same problems.

first: have libraries compiled, , linked simple test application, example pcre c++ regex library. when try link boost regex library, -lboost_regex compile flag, following error:

ld: 0706-006 cannot find or open library file: -l boost_regex ld:open(): no such file or directory make: error code last command 255. 

this resolved adding -brtl compile flag, far know needed if try link static library, looks me if libboost_regex.so libboost_regex.a

second: when add line #include "boost/regex.hpp" code, compilation error:

"/opt/ibm/xlc/13.1.2/include/xtr1common", line 217.19: 1540-0130 (s) "false_type" not declared. "/opt/ibm/xlc/13.1.2/include/xtr1common", line 223.19: 1540-0130 (s) "true_type" not declared. "/opt/ibm/xlc/13.1.2/include/xtr1common", line 229.19: 1540-0130 (s) "true_type" not declared. "/opt/ibm/xlc/13.1.2/include/xtr1common", line 235.19: 1540-0130 (s) "true_type" not declared. "/opt/ibm/xlc/13.1.2/include/xtr1common", line 244.11: 1540-0130 (s) "false_type" not declared. "/opt/ibm/xlc/13.1.2/include/xtr1common", line 250.11: 1540-0130 (s) "true_type" not declared. make: error code last command 1. 

my test application simple. these contents of makefile:

all:     /opt/ibm/xlc/13.1.2/bin/xlc -q64 -iinclude -llibs -lpcrecpp main.cpp -o regexp_test  clean:     rm regexp_test 

here source code of basic test application:

how can these problems resolved? hints or advice appreciated.

i have found soltuion both of problems.

the problem linking:

i have found post: https://durgaprasad.wordpress.com/2006/09/28/problems-with-linking-of-shared-libraries-in-aix/

it details on aix, shared libraries can have both .so , .a suffix, , instruct compiler search .so files you'll need include -brtl flag. instructs include -wl flag, in order pass linkage flags directly linker (ld), have found version of xlc functionality deprecated.

the problem code:

the preprocessor instruction #define __ibmcpp_tr1__ 1 caused boost regex library fail compilation error. define needed built-in tr1 regular expressions of aix using, turns out required #include <regex> part, can omit second define.
