Subject: [ruby-core:52694] [ruby-trunk - Bug #7913] `./configure --enable-multiarch` fails


Issue #7913 has been updated by terceiro (Antonio Terceiro).


My patch make the ./configure part pass, but the build still fails at linking stage:

gcc -O3 -fno-fast-math -ggdb3 -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wunused-variable -Werror=pointer-arith -Werror=write-strings -Werror=declaration-after-statement -Werror=implicit-function-declaration -ansi -std=iso9899:199409  -L. -fstack-protector -rdynamic -Wl,-export-dynamic -fstack-protector -pie   main.o dmyext.o  -Wl,-R -Wl, -L -lruby-static -lpthread -lrt -ldl -lcrypt -lm    -o ruby
main.o: In function `main':

I don't think my patch is causing this.

Bug #7913: `./configure --enable-multiarch` fails
https://bugs.ruby-lang.org/issues/7913#change-36785

Author: terceiro (Antonio Terceiro)
Status: Open
Priority: Urgent
Assignee: nobu (Nobuyoshi Nakada)

Target version: 
ruby -v: ruby 2.0.0dev (2013-02-22 trunk 39384)


Hi, since the changes in bug #7874 `./configure --enable-multiarch` does not work in trunk anymore:

$ autoreconf && ./configure --target=x86_64-linux-gnu --enable-multiarch
[...]
configure: creating ./config.status
config.status: creating Makefile
config.status: creating ruby-2.0.pc
Variable 'archlibdir' not defined in './ruby.tmp.pc'

... and ./configure exits with a failure status (1).

The attached patch fixes this by moving the archlibdir variable up in template,
pkg-config template so that it is defined at the point of substitution in the
LDFLAGS part below.
