Hello everyone, because my configuration enables the extension pack for virtualbox and have extra config for kernel so I have to compile virtualbox and the kernel every time the channel updates. I heard of ccache recently and I want to use it to speed up the upgrading task. I add these lines in my configuration:
programs.ccache.enable = true;
programs.ccache.packageNames =
let
versionNums = splitString "." (import <nixpkgs> {}).linuxPackages_latest.kernel.version;
kernelPackageName = concatStringsSep "_" ([ "linux" ] ++ (take 2 versionNums));
in [ kernelPackageName "virtualbox" ];
But the compilation for kernel fails with:
Compiler lacks asm-goto support
Is that fixable?
BTW, is there any way to get the version of the latest kernel without refer to linuxPacakges_latest.kernel.version, which will cause an infinite recursion?
EDIT:
Add nix.sandboxPaths = [ config.programs.ccache.cacheDir ] and the compilation for linux kernel seems to be OK, but compiling virtualbox fails because configure could not find header files needed for 32bit support:
***** Checking 32-bit support *****
compiling the following source file:
#include <stdint.h>
int main(void)
{
return 0;
}
using the following command line:
gcc -m32 -O -Wall -o /build/VirtualBox-6.0.12/.tmp_out /build/VirtualBox-6.0.12/.tmp_src.c

Any clues? I’m digging it but I don’t know where to check now.
