To define the message format so they appear properly in the Problems view, you have to add them as well to the proj_options.lnt, as the following listing shows:
// Coerce messages for Eclipse -hF1 +ffn // Normally my format is defined as follows: //-"format=%(\q%f\q %l %C%) %t %n: %m" // For eclipse-usage, the GCC error format is necessary, // since we have only the default eclipse error parser available. -"format=%(%f:%l:%C:%) %t %n: %m" // Enable warning 831 if you are interested. -frl // Do not break lines -width(0) // And make sure no foreign includes change the format +flm
