The signature of dm_get_device from device-mapper.h changed between 2.6.32 and 2.6.34 (didn't try 2.6.33). app-crypt/truecrypt-4.3a fails to compile (too many arguments in Linux/Kernel/DM-Target.c:213) Reproducible: Always Steps to Reproduce: 1. emerge -1 =sys-kernel/gentoo-sources-2.6.34-r1 2. eselect kernel set <set to 2.6.34-r1> 3. emerge -1 =app-crypt/truecrypt-4.3a Actual Results: * ERROR: app-crypt/truecrypt-4.3a failed: * Unable to emake HOSTCC=x86_64-pc-linux-gnu-gcc CROSS_COMPILE=x86_64-pc-linux-gnu- LDFLAGS= KERNEL_SRC=/usr/src/linux NO_WARNINGS=1 truecrypt * * Call stack: * ebuild.sh, line 54: Called src_compile * environment, line 3572: Called linux-mod_src_compile * environment, line 2751: Called die Expected Results: truecrypt should build and install

Created attachment 242927 [details, diff] Patch for truecrypt-4.3a with kernel 2.6.34 Kernel devs have hidden kmalloc in <linux/slab.h>. Taken and modified from here: http://www.mizrahi.com.ve/crux/pkgs//truecrypt/truecrypt-kernel-2.6.34.patch Warning: The patch is not kernel-version-dependent like the other gentoo patches in ${FILESDIR}. It will not compile with kernel <2.6.34. With this patch, truecrypt-4.3a works for me.
No longer in tree. Hasn't been available for some time. Closing.
