Bug ID: 57795
Summary: Fail cross building Ada
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: alexpux at gmail dot com
I try to build i686 multilib mingw toolchain with Ada from linux x86_64
toolchain.
First I build cross-compiler linux-x64 -> mingw-x32. Next I try to build
mingw-x32 native toolchain from cross and get fail building libada on last
step.

I see that gcc got wrong headers and libs
(I/usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.1/adalib/../adainclude
-I/usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.1/adalib/) from linux native
toolchain. But it can be pointed to headers and libs from cross toolchain.
I do this operation with different gcc - 4.7.3 and 4.8.1 with the same result.
My dirty hack to resolve it is to copy ada headers and libs from cross
toolchain to native toolchain. Then build finishing fine.
Regards,
Alexey.
