Reproduce the problem: 1. download source archive (libofa-0.9.3) :) 2. ./configure 3. make

I get a build error like this: make[3]: Entering directory /libofa-0.9.3/lib' if /bin/bash ../libtool --mode=compile g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../include -g -O2 -Wall -g -MT mainprint.lo -MD -MP -MF ".deps/mainprint.Tpo" -c -o mainprint.lo mainprint.cpp; \ then mv -f ".deps/mainprint.Tpo" ".deps/mainprint.Plo"; else rm -f ".deps/mainprint.Tpo"; exit 1; fi g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../include -g -O2 -Wall -g -MT mainprint.lo -MD -MP -MF .deps/mainprint.Tpo -c mainprint.cpp -fPIC -DPIC -o .libs/mainprint.o JAMA/tnt_math_utils.h: In function 'Real TNT::hypot(const Real&, const Real&) [with Real = float]': JAMA/jama_svd.h:73: instantiated from 'JAMA::SVD<Real>::SVD(const TNT::Array2D<T>&) [with Real = float]' mainprint.cpp:151: instantiated from here JAMA/tnt_math_utils.h:34: error: call of overloaded 'abs(const float&)' is ambiguous /usr/include/stdlib.h:691: note: candidates are: int abs(int) /usr/include/c++/4.2/cstdlib:174: note: long long int __gnu_cxx::abs(long long int) /usr/include/c++/4.2/cstdlib:143: note: long int std::abs(long int) make[3]: *** [mainprint.lo] Error 1 make[3]: Leaving directory/libofa-0.9.3/lib' make[2]: * [all-recursive] Error 1

What version of the product are you using? On what operating system? gcc (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7) on Ubuntu 8.10

Please provide any additional information below. The fix: add a "using __gnu_cxx::abs;" in JAMA/tnt_math_utils.h @ line 33;

After this the build works fine

i get the same issue do you have any solution for this ??

did you try the mentioned fix?

yes i tried it but it is not working

yes i tried it but it is not working

I dont know of other solution then. I stopped working with libfoa a long time ago, as i didn't have the necessary time

Did you worked on the same domain after leaving libofa..?? Can you suggest me any other such library which can be used in lieu of libofa..??

nope, i gave up on the idea

I really know jack about it, but this makes it go on Slackware 13.37.0/gcc version 4.5.2.. I blew away examples, so no examples..
