尝试在solaris i86中创建共享对象时出现奇怪的问题

Question

我正在尝试在solaris中创建一个共享对象.so文件，这些是我正在做的以下步骤...

1. 我有一个源代码jags ...如果我们尝试构建它将生成一个可执行文件..下面是创建该命令的命令

g++ -g -O2 -o .libs/jags-terminal jags_terminal-parser.o jags_terminal-scanner.o jags_terminal-ReadData.o .libs/jags-terminalS.o  /JAGS-2.2.0/libltdl/./.libs/dlopen.a ../../libltdl/.libs/libltdlc.a ../../src/lib/.libs/libjags.so -L/usr/sfw/lib /usr/sfw/lib/libstdc++.so -lgcc_s -lm -Wl,-R -Wl,/usr/local/lib -Wl,-R -Wl,/usr/sfw/lib

1. 现在我正在尝试使用相同的流程创建一个共享对象，这个命令有点像这样

g++ -shared -o .libs/libjagsterminal.so jags_terminal-parser.o jags_terminal-scanner.o jags_terminal-ReadData.o .libs/jags-terminalS.o  /JAGS-2.2.0/libltdl/./.libs/dlopen.a ../../libltdl/.libs/libltdlc.a ../../src/lib/.libs/libjags.so -L/usr/sfw/lib /usr/sfw/lib/libstdc++.so -lgcc_s -lm -Wl,-R -Wl,/usr/local/lib -Wl,-R -Wl,/usr/sfw/lib

以下是执行上述行后的问题..

Answer 1

如果gcc使用/usr/ccs/bin/ld，则将-shared替换为-G

Answer 2

共享对象需要构建position-independent，因此您希望将-fPIC标志添加到GCC调用中。
