* README: Mention $PKG_CONFIG_PATH, and make it clear that $BDW_GC_LIBS, etc. aren't normally needed.

@ -93,10 +93,15 @@ Guile requires the following external packages:
|
|||
- pkg-config
|
||||
|
||||
Guile's ./configure script uses pkg-config to discover the correct
|
||||
compile and link options for libgc and libffi. If you don't have
|
||||
pkg-config installed, or you have a version of libgc that doesn't
|
||||
provide a .pc file, you can work around this by setting some
|
||||
variables as part of the configure command-line:
|
||||
compile and link options for libgc and libffi. For this to work,
|
||||
the `PKG_CONFIG_PATH' environment variable must be set to point to
|
||||
the places where libgc's and libffi's `.pc' files can be found:
|
||||
|
||||
PKG_CONFIG_PATH=/path/to/libgc/lib/pkgconfig:/path/to/libffi/lib/pkgconfig
|
||||
|
||||
Alternatively, when pkg-config is not installed, you can work around
|
||||
this by setting some variables as part of the configure
|
||||
command-line:
|
||||
|
||||
- PKG_CONFIG=true
|
||||
