Hello everybody It seems than maintainer of crux port of mate project did some useful changes in crux-mate port, and problems that I mentioned in my previous mail are fixed. But the port still cannot be compiled. The package mate-settings-daemon breaks build process. Here is more detailed description of build failure: I got this error: /usr/include/nss/seccomon.h:51:21: fatal error: prtypes.h: No such file or directory Well, I have nss package installed, but there is no prtypes.h file in the /usr/include/nss folder. The file prtypes.h is part of nspr package, which is installed, also. How to change build so that it can be able to find prtypes.h file? Where/How to add include path to prtypes.h (the path is /usr/include/nspr) in the Pkgfile. PP: I will post the problem as an issue on crux-mate project.
