Thank jwakely! yes , I've compiled my x86_64 with "configure --disable-multilib" for some compile errors. Is thers a simple way to build the 32bit lib on my amd64 env now, against re-configure and re-build the whole gcc? It need 2-3 hours to compile the gcc on my computer. By the way , I downloaded a precompiled lib package from the fc website for temporary using , and it looked like worked well. 2013/9/7, Jonathan Wakely <jwakely.gcc@xxxxxxxxx>: > On 7 September 2013 05:11, Zhang hw wrote: >> Hello , everybody! >> I have compiled and installed a gcc-4.8.1 with configure >> --build=x86_64-redhat-linux-gnu.There is a app need 32bit libstdc++ >> now , but there is nothing in "lib" directory , how to build and >> install it? > > x86_64-*-linux-gnu always builds a multilib compiler unless you use > --disable-multilib > >> I have compiled with xxx/libstdc++-v3/configure >> --target=i686-redhat-linux-gnu and returned success , but after >> installed it , I've got only the libraries in directory "lib64" , >> there was nothing in "lib" directory? > > That doesn't make sense, i686-*-linux-gnu is a 32-bit non-multilib target. > >> Can I compile and install a 32bit libstdc++ with parameters changing >> for configure and make install?
