发帖数: 3020 | 1 3.4. Creating a Shared Library
Creating a shared library is easy. First, create the object files that will
go into the shared library using the gcc -fPIC or -fpic flag. The -fPIC and
-fpic options enable ``position independent code'' generation, a requirement
for shared libraries; see below for the differences. You pass the soname
using the -Wl gcc option. The -Wl option passes options along to the linker
(in this case the -soname linker option) - the commas after -Wl are not a
typo, and you mus... 阅读全帖 |

the libraries
libcurses.so libX11.so libXmu.so libXi.so libGL.so libGLU.so libglut.so
libglut.a
you have on your computer may have multiple versions. So different parts of
your code may be linked to different versions of the libs.
Make sure for each lib, you just consistently use the same version. Check
your LD_LIBRARY_PATH, (help http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html)
Some of the libs above may be soft or hard links to some files in your file

发帖数: 1 | 5 -G is used to generate shared object (check g++ manual for solaris, yes
they are different). It's for compatibility, you should use -shared.
Actually .c should be compiled to .o first, then link to .so. I think
-G is passed to linker in link stage; in compile stage, it actually
means -fPIC or something similar to generate relocatable objects.
So in linux you should use
g++ -fPIC -Ixxxx -Ixxxx source.c -o source.o
g++ -shared source.o -o dest.so |

发帖数: 347 | 6 post some error logs plz.
normally it's due to the missing header or missing lib file. or wrongly
configured include path and/or ld_library_path.
mac is unix, python is more linux-friendly, meaning they may well have
different default search path. also python by default compile w/o -fPIC. SSL
lib may need -fPIC.
anyway some error logs will use useful to tell what's wrong. |

发帖数: 5958 | 19 最好用static link. Linux版本太多, 如果想只deliver binary, 一要找一个老版本
的kernel, 二要static link所有的library. readline这种东西自己编译一个static版
本就可以了. 我最近在做的一个事情才扯淡. 对方要一个.so的binary. 但是
dependency一大堆, 结果是把所有要用到的library全都static link到这个.so中. 但
是这个.so本身又需要能被动态链接, 结果大部分的library还需要用-fPIC重新编译.
做完之后我很惊异于gnu这套toolchain的flexibility. |

发帖数: 5958 | 20 开源的无所谓。如果你不想开源，或者客户没有下载源程序运行make的能力，那么我的
建议是centos 5.6，至少用vagrant之类的搞个centos 5.6做编译。这样基本上保证了
编译出来的二进制程序在哪儿都能跑。还有toolchain得花心思弄一下。网上可以弄到
gcc-4.7的yum respository，剩下各种自己依赖的library最好都用--enable-static -
-disable-shared外加export CFLAGS=-fPIC编译。这样可以弄出来静态编译的动态链接
库。很多环境，像java /python/matlab等和C++接口都需要你提供动态链接库，但是如
