Re: [Boost-users] question on boost::regex expression(query);

Thanks. If I have to guess at this point, I think it is a quirk of my cygwin install or version- it is also possible I have intermixed boost files but still a bit confusing. AFAIK, everything is working right now except the try/catch so maybe I can let it go until I can safely upgrade my tools. $ g++ -v Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/specs Configured with: /gcc/gcc-3.3.3-3/configure --verbose --prefix=/usr --exec-prefi x=/usr --sysconfdir=/etc --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/s hare/man --infodir=/usr/share/info --enable-languages=c,ada,c++,d,f77,java,objc, pascal --enable-nls --without-included-gettext --enable-libgcj --with-system-zli b --enable-interpreter --enable-threads=posix --enable-java-gc=boehm --enable-sj lj-exceptions --disable-version-specific-runtime-libs --disable-win32-registry Thread model: posix gcc version 3.3.3 (cygwin special) $ g++ -I. t.cpp -L./lib -lboost_regex-gcc-mt Info: resolving vtable for boost::regex_errorby linking to __imp___ZTVN5boost11r egex_errorE (auto-import) Administrator@TESTBED01 /cygdrive/c/mydocs/scripts/cc/affx/boost $ ./a [ <<<<<<<<<< This pops up a dialog box about missing dll ] Administrator@TESTBED01 /cygdrive/c/mydocs/scripts/cc/affx/boost $ cygcheck a.exe Found: c:\mydocs\scripts\cc\affx\boost\a.exe c:/mydocs/scripts/cc/affx/boost/a.exe Error: could not find cygboost_regex-gcc-mt-1_33_1.dll C:\WINNT\cygwin1.dll C:\WINNT\system32\ADVAPI32.DLL C:\WINNT\system32\KERNEL32.dll C:\WINNT\system32\ntdll.dll C:\WINNT\system32\RPCRT4.dll Error: could not find cygboost_regex-gcc-mt-1_33_1.dll Administrator@TESTBED01 /cygdrive/c/mydocs/scripts/cc/affx/boost $ cp ../cygboost_regex-gcc-mt-1_33_1.dll .

Same problem during link and runtime with only dll. The static choice should avoid dll problems so maybe I'll give that another look. Thanks again.

Well it works for me with the Boost-1.33.1 install supplied with current cygwin, the test program is:

#include #include <iostream>

int main() { try{ boost::regex e("(?<=GU.*?TACTAAC.{20,40}AG|^)?(GU.*?TACTAAC.{20,40}AG|$)"); } catch(boost::regex_error e) { std::cout << "Caught a regex_error" << std::endl; std::cout << e.what() << std::endl; } catch(std::exception e) { std::cout << "Caught a std::exception" << std::endl; std::cout << e.what() << std::endl; } }

and then:

$ g++ -I /usr/include/boost-1_33_1 t.cpp -lboost_regex-gcc-mt Info: resolving vtable for boost::regex_errorby linking to __imp___ZTVN5boost11regex_errorE (auto-import)

$ ./a Caught a regex_error Invalid regular expression

Which is what I would expect in that case.

HTH, John.
