- o If you have problems indicating that configure cannot find a part of
- the xforms or Xpm library, use the --with-extra-lib and --with-extra-inc
- options of configure to specify where these libraries reside.
-
- o Configure will seemingly fail to find xpm.h and forms.h on linux
- if the kernel headers are not available. Two cases are possible:
-
- - you have not installed the kernel sources. Then you should
- install them or at least the kernel-headers package (or
- whatever it is called in your distribution).
-
- - you have the sources, but you did a 'make mrproper' in the
- kernel directory (this this removes some symbolic links that
- are needed for compilation). A 'make symlinks' in linux kernel
- sources fixes that.
-
- o if you are using RedHat Linux 7.x, you must make sure you have the
- latest updated gcc and related packages installed (at least -85),
- or LyX will not compile or will be mis-compiled.
-
- o if you get an error message when compiling LyX that looks like this :
-
- ../../src/minibuffer.h:17: using directive `Object' introduced
- ambiguous type `_ObjectRec *'
-
- then you need to upgrade the version of the xforms library you have
- installed.
