【问题描述】：
您好，我在 Ubuntu 16.04 上安装了 Modelsim 32 位版本。 我还安装了相关的 32 位库，它工作正常。 （模拟对其他项目效果很好）
但是，当我尝试在pulpinino 运行helloworld 时，我遇到了这个问题。
make helloworld // 100% fine
make vcompile // 100% fine
make helloworld.vsim // this gives following issue. in vsim
** Fatal: ** Error: (vsim-3828) Could not link
### 'vsim_auto_compile.so': cmd = '/home/ashan/intelFPGA_pro/17.0/modelsim_ase/gcc-4.7.4-linux/bin/gcc -shared -fPIC -m32 -B/usr/lib32
-o "/tmp/ashan@e420_dpi_8127/linuxpe_gcc-4.7.4/vsim_auto_compile.so" /home/ashan/git/pulp/pulpino/vsim/work/_dpi/auto_compile@/linuxpe_gcc-4.7.4/*.o '
我认为-o "/tmp/ashan@e420_dpi_8127/linuxpe_gcc-4.7.4/vsim_auto_compile.so" 中存在问题，因为没有这样的文件。
有人可以帮忙解决这个问题吗？
[更新] 这是vsim的输出日志

主要问题是这个

这里 ld(linker) 的 SEARCH_DIR 指向 /usr/lib32/
似乎存在兼容性问题。有人解决了这个问题吗？
