我在AIX 6.1机器上安装了一个名为expat-2.1.0的C包。执行gmake时会弹出以下输出。

我在Linux机器上安装的这个软件包没有出现任何错误。
在脚本中执行下面的命令时，由于选项-no-undefined错误即将出现，因为包含它不应该抛出错误，我想命令无法链接到标题，因此错误来了。
bash-3.2# /bin/sh ./libtool --mode=link gcc -std=gnu99 -I./lib -I. -g -O2 -Wall

如果我删除-no-undefined该命令工作正常。任何人都可以帮我找到如何使用-no-undefined选项运行此命令。
然后，我使用--verbose和-bloadmap选项分别执行以下命令。
bash-3.2# gcc -shared --verbose -o .libs/libexpat.so.1 lib/.libs/xmlparse.o lib
/.libs/xmltok.o lib/.libs/xmlrole.o -lc -Wl,-bnoentry -O2 -W1,-bloadmap -Wl

似乎gcc正在链接到共享的libgcc库，所以我在上面的命令中添加了选项-static-libgcc，结果是它被执行而没有任何错误。
但有人可以告诉我如何在第一个命令中使用相同的选项，即
/bin/sh ./libtool --silent --mode=compile gcc -std=gnu99 -I./lib -I. -g -O2 -Wal
l -Wmissing-prototypes -Wstrict-prototypes -fexceptions -DHAVE_EXPAT_CONFIG_H -
