Hi guys, While trying to compile the NBCog vm on my MacOS machine I have found a strange issue... I do not know if it comes from my machine configuration or if it is more general than that... Mainly after loading the cairo package the compilation process fails to unpack the cairo.tgz archive... It seems that the extension of the package changes (the downloaded package has a .tar.xz extension, which gets dropped and replaced by .tgz) and my "tar" install can't cope with that.... I have fixed it temporarily as shown bellow: CMCairo>>unpack "..." gen set: #unpackTarget toString: '${libSourcesDir}/touch.cmake'. gen puts: 'add_custom_command(OUTPUT "${unpackTarget}" COMMAND tar -Jxf "${libName}.tgz" COMMAND touch "${unpackTarget}" COMMENT "Unpacking ${libName} ... " ) '. by CMCairo>>unpack "..." gen set: #unpackTarget toString: '${libSourcesDir}/touch.cmake'. gen puts: 'add_custom_command(OUTPUT "${unpackTarget}" COMMAND cp "${libName}.tgz" "${libName}.tar.xz" COMMAND unxz "${libName}.tar.xz" COMMAND tar xf "${libName}.tar" COMMAND touch "${unpackTarget}" COMMENT "Unpacking ${libName} ... " ) '. Is this a known issue, or my "tar" install is wrong? Cheers, Ciprian -- Dr. Ciprian TEODOROV Ingénieur Développement CAO tél : 06 08 54 73 48 mail : ciprian.teodorov@gmail.com www.teodorov.ro
