[Coin-discuss] Compilation issues for IPOPT

[Mikhail Nediak]

Hi,

As a follow up to my previous message, I have managed to build Ipopt and
Dfo libraries on this system by disabling shared libraries with
--enable-shared=no (since Dfo only needs the static one). However, my
attempt at building the example for Dfo failed since the standard -lblas
and -llapack were deemed "incompatible" by ld:

[nediakm at nar317 Dfo_2006Aug01]$ make dfotest_ipopt
f77 -o dfotest_ipopt -O dfotest.o\
             ./libdfo_ipopt.a ranlux.o ../Ipopt_2006Aug01/lib/libipopt.a
-llapack -lblas
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../libblas.so when
searching for -lblas
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../libblas.a when searching
for -lblas
/usr/bin/ld: skipping incompatible /usr/lib/libblas.so when searching
for -lblas
/usr/bin/ld: skipping incompatible /usr/lib/libblas.a when searching for
-lblas
/usr/bin/ld: cannot find -lblas
collect2: ld returned 1 exit status
make: *** [dfotest_ipopt] Error 1

I am not quite sure how the incompatibility is determined and whether it
is possible to twist the build process around it.
Also, it is not clear how to produce (or find and use) the substitutes
supposedly resulting from "ThirdParty" packages. Finally, on my standard
workstation the build for dfotest_ipopt fails because libipopt.a no
longer provides ev_hlv_dummy__ (it did in the build of an earlier
version).

Any suggestions?

Thanks much!

Mikhail
