This new package provides skalibs, a collection of free software / open source C development files used for building all softwares from skarnet.org. Note that, though skalibs (and all skarnet softwares) follows the "./configure; make; make install" convention, it does not behave like a traditional autotools project: - static libraries are installed in $prefix/usr/lib/skalibs. - pkg-config and libtool are not used: instead a custom system called "sysdeps" is used and locations to libraries and headers are to be passed explicitly via options of the './configure' script. The host variant is provided to allow building the host variants of the other skarnet softwares.

Subject: [PATCH] No runtime tests for type sizes
|
|
|
|
Replace build and execution of runtime test programs for determining
|
|
some type sizes of the target with compile time test programs.
|
|
|
|
This improves support for cross-compilation.
