Does wxGTK have GNOME support?

Why doesn't reading floating point numbers work when using wxWindows?

+ +If your program reads the floating point numbers in the format 123.45 +from a file, it may suddently start returning just 123 instead of the +correct value on some systems -- which is all the more mysterious as the same +code in a standalone program works just fine. + +

+The explanation is that GTK+ changes the current locale on program startup. If +the decimal point character in the current locale is not the period (for +example, it is comma in the French locale), all the standard C functions won't +recognize the numbers such as above as floating point ones any more. + +

+The solution is to either use your own function for reading the floating point +numbers (probably the best one) or to call setlocale(LC_NUMERIC, "C") +before reading from file and restore the old locale back afterwards if needed. + +

Does wxGTK have GNOME support?

Currently wxGTK does not have any features that would involve dependence on any desktop -environment's libraries, so it can work on GNOME, KDE and with other window managers +environment's libraries, so it can work on GNOME, KDE and with other window managers without installation hassles. Some GNOME and KDE integration features are file based, and so may be added without dependence on libraries. Other features may be supported in the future, probably as a separate library.

Warning about GTK libraries supplied with RedHat

+ +It seems that some versions of RedHat include a badly patched version of GTK (not wxGTK) +which causes some trouble with wxWindows' socket code. Common symptoms are that when +a client tries to establish a connection to an existing server which refuses the request, +the client will get notified twice, first getting a LOST event and then a CONNECT event. +This problem can be solved by updating GTK with an official distribution of the library. +

What range of Intel Linux platforms will a given application binary be usable on?

+ +Robert Roebling replies:

+ +"The important thing is the libc version that your app +is linked against. The most recent version is 2.2.5 +and programs linked against it will not run with version +2.1.X so that you will fare best if you compile your app +on a 2.1.X system. It will then run on practically all +Linux distros (if you link you app statically against +the image libraries and std C++ lib)."
