Dear users,
to start using regular expressions I tried a very simple program only
declaring one regular expression.
#include
int main(int , char* [])
{
boost::regex re("\\d+");
return 0;
}
Linking and compiling this with the command:
g++ test.cpp -o test -L ~/libs/boost/lib/ -l boost_regex-gcc43-mt
works without problems, but running it then leads to the following:
error while loading shared libraries:
libboost_system-gcc43-mt-1_37.so.1.37.0: cannot open shared object file:
No such file or directory
But the directory clearly shows its existence:
-rw-rw-r-- 1 engineer engineer 1587006 2008-11-21
07:53 /home/engineer/libs/boost/lib/libboost_regex-gcc43-mt-1_37.a
lrwxrwxrwx 1 engineer engineer 38 2008-11-21
07:50 /home/engineer/libs/boost/lib/libboost_regex-gcc43-mt-1_37.so ->

-rwxrwxr-x 1 engineer engineer 722184 2008-11-21

lrwxrwxrwx 1 engineer engineer 30 2008-11-21
07:53 /home/engineer/libs/boost/lib/libboost_regex-gcc43-mt.a ->

lrwxrwxrwx 1 engineer engineer 38 2008-11-21
07:52 /home/engineer/libs/boost/lib/libboost_regex-gcc43-mt.so ->
libboost_regex-gcc43-mt-1_37.so.1.37.0
Then I tried doing the same using static libraries:
g++ -static test.cpp -o test -L ~/libs/boost/lib/ -l
boost_regex-gcc43-mt
but got an extremely long list of errors:

If anyone could point me to a solution of this problem, or give one here
I'd very much appreciate it. Thank you.
Best,
