Hi Mark, Thank you for your answer. Fetching the source in tar.gz does not work :
fetching from: http://prdownloads.sourceforge.net/wxwindows/wxWidgets-2.9.1.tar.gz Fetch failed! HTTP response: 404 Not Found [404 Not Found] at inc/My/Build/Base. pm line 305 Unable to fetch archive at inc/My/Build/Base.pm line 307. I have tried with zip but the process stops : fetching from: http://prdownloads.sourceforge.net/wxwindows/wxWidgets-2.9.1.zip Extracting wxWidgets... No '/bin/unzip' program found at inc/My/Build/Base.pm line 322 mkdir C:\AlienWxWidgets\build: File exists; Impossible de crÚer un fichier dÚjÓ existant at C:/strawberry/perl/site/lib/Archive/Zip/Archive.pm line 164 I suspect Archive.pm having troubles with the existing Build file. So tried to rename the generated Build file into Buildwx and then launching : perl Buildwx As a result, fetching the source works but the build process stops when patching wxWidgets : No '/bin/unzip' program found at inc/My/Build/Base.pm line 322 Patching wxWidgets... Applying patch: C:\AlienWxWidgets\patches\wxMSW-2.9.1-setup.patch perl -pe "" -- C:\AlienWxWidgets\patches\wxMSW-2.9.1-setup.patch | ..\inc\bin\patch.exe -N -p0 -u -b -z .bak Le chemin d'accès spécifié est introuvable. Error: 65280 at inc/My/Build/Base.pm line 342. It is a path not found error. I have tried another way, fetching and building wxWidgets by myself and then setting the WXDIR and WXWIN env variables but I get : Checking prerequisites... Looks good A wxWidgets build seems to be in 'c:\wxWidgets-2.9.1', so it should be safe to a nswer 'no' to the following question Do you want to fetch and build wxWidgets from sources? [no ] no Deleting Build Removed previous script 'Build' Creating new 'Build' script for 'Alien-wxWidgets' version '0.51' C:\build_alien>perl Build Configuration error: could not find libraries for configuration: 'u' '29' at inc /My/Build/Win32.pm line 78. Do you have any idea ? Regards Richard
