Hi!

I tried to upgrade from 0.9.8d to 0.9.8e on my GNU/Linux Alpha box and go=
t a straigt compiler error:

shell$ ./config
# some output... among that:
Operating system: alpha-whatever-linux2
Configuring for linux-alpha+bwx-gcc
Configuring for linux-alpha+bwx-gcc

shell$ LANG=3DC make
making all in crypto...
make[1]: Entering directory `/spielwiese/smgl/grimoires/grimoire/openssl-=
0.9.8e/crypto'
gcc -I. -I.. -I../include -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHA=
VE_DLFCN_H -march=3Dev6 -O3 -DL_ENDIAN -DTERMIO -c -o cryptlib.o cryptl=
ib.c

make[1]: *** [cryptlib.o] Error 1
make[1]: Leaving directory `/spielwiese/smgl/grimoires/grimoire/openssl-0=
..9.8e/crypto'
make: *** [build_crypto] Error 1

Now the gcc on alpha doesn't know -march, as Alphas are just a small set =
of successive CPUs and not a diversed family of many, many CPUs with vary=
ing degree of similarity like x86.
It needs -mcpu.
Well, 0.9.8d got this right, but for 0.9.8e, someone apparently did somet=
hing along

sed -i 's/mcpu/march/' config

which causes specifically this change:

Please revert this change for the next release to make the build work aga=
in.

Actually, I must say that I'd prefer omitting the -mcpu settings altogeth=
er and use CFLAGS instead.
The distro I'm using is a source code based one and has something called =
"archspecs" for the user to choose from.
There we set things like -mcpu or -march; and we already have to insert t=
hat to the openssl Makefile:

../config
sed -i "s/^CFLAG=3D/CFLAG=3D$CFLAGS /" Makefile

But still, if I have -mcpu=3Dev67 in my $CFLAGS, the -mcpu (or -march, cu=
rrently) of openssl will override it.
That can be a problem when I want to compile for a ev5 CPU on a ev67 box;=
openssl will build binaries that won't run on the older cpu.


Alrighty then,

Thomas.
