Hi everyone,
I'm cross compiling using arm-softfloat-linux-gnu, with the usual
procedure using a SYSROOT of /usr/arm-softfloat-linux-gnu and the xmerge
script.
First of all, I should ask - has anyone found a fix for cross-compiling
mpfr already? If so how? ... would something like
ECONF_EXTRA="--with-gmp-lib=DIR" work?
The original problem is exactly related to Simon's here:
http://forums.gentoo.org/viewtopic-t-639572.html?sid=acbcac0d727bdaafa52ffc784641c0e7
Mpfr would originally not compile because it linked to
/usr/lib/libgmp.so always, instead of the libgmp.so in the compiler's
search path.
That was due to -rpath /usr/lib being present, so i created a very
simple patch to remove the rpath (was that a bad idea?).
In any event, mpfr-2.3.0_p3.ebuild now looks like [1], while
mpfr-2.3.0_p3-disable-rpath-patch looks like [2].
The patch applies perfectly and the compile is successful, but then
during the install phase, the installer bails out with message [3].
There is no .libs/libmpfr.lai file at all, but there is of course a
.libs/libmpfr.la file.
Why would the .la file suddenly be named .lai? Is it just a copy?
It seems like an easy enough patch to just copy from one directory to
another in Makefile.in, but I thought I'd write the list first and see
if anyone else has a more elegant solution.
