[/Quote]gcc 的时候
gcc -brtl
但 gcc -b 参数的意思是

[prettyicy]

在makefile里加上吗？
谢谢你了。
我菜鸟一只还是不懂

[xue98]

你这是连接sybase 数据库的程序吧。

[prettyicy]

是sybase
想写个程序，往表里插记录

[xue98]

CC = cc $(Q64) -g -brtl

你用的AIX 系统？/

0509-151 The program does not have an entry point or
the o_snentry field in the auxiliary header is invalid.
0509-194 Examine file headers with the 'dump -ohv' command.

报错的前面是什么？

[prettyicy]

谢谢你。
可是运行时还是报错
0509-036 Cannot load program icytest because of the following errors:
0509-151 The program does not have an entry point or

顺便问下怎么给分。。。

是AIX

make完以后，运行可执行程序
提示

你把 icytest icytest.o 这两个文件删除了， 然后再 make 一下

你机器上面有 /usr/vacpp/bin/xlC_r 吗？

[prettyicy]

好像没有/usr/vacpp/bin/xlC_r、

删除再make，执行依然报相同的错

[xue98]

using the wrong AIX linker. It should be using the executable linker, not the library linker.

好像是连接器的问题

your gcc is using AIX's ld, I'm afraid the fix we have will only work if gcc
is using GNU's ld.

is this gcc the "standard" gcc from AIX?, could you get another one that is
configured to use GNU ld instead?; you could find by running :

$ gcc -print-prog-name=ld

[xue98]

If the linker command (ld) was used instead of the compiler driver (cc) as follows:
$ cc -c main.c
$ ld main.o func1.so func2.so func3.so -brtl
then the program would print the following error message, since the generated
executable would not contain the necessary start up routine:
$ LIBPATH=$PWD ./a.out
exec(): 0509-036 Cannot load program ./a.out because of the following errors:
0509-151 The program does not have an entry point or
the o_snentry field in the auxiliary header is invalid.
0509-194 Examine file headers with the 'dump -ohv' command.

[fleim]

xlc对应-g;

xlC对应-g或-G。

否则编译后，运行时报如下错误：

exec(): 0509-036 Cannot load program ./t because of the following errors:
0509-151 The program does not have an entry point or
the o_snentry field in the auxiliary header is invalid.
0509-194 Examine file headers with the 'dump -ohv' command.

AIX 下通常用xlC来编译c++代码，例如我写了一个string的类，包含俩文件 string.h 和 string.cpp ，现在我想将其编译成动态链接库（.so文件），方法为：

xlC -G -o libstring.so string.cpp

AIX下.so文件最好用 libxxxxx.so的方式来命名，因为在后面与其他文件一起编译链接成可执行文件时会好办些

我又写了一个test.cpp 包含main方法 用来测试string.so中的类是不是可以正常使用，现在我们假设libstring.so文件的path为：/home/hello/lib 那么编译链接成可执行文件时，命令为：

xlC -brtl -L/home/hello/lib -lstring -o test test.cpp
(如果找不到，用xlC -brtl /home/hello/lib/libstring.so -o test test.cpp)
xlC 中： -brtl表示： Enables run-time linking for the output file. DCE thread libraries and heap debug libraries are not compatible with run-time linking. Do not specify the -brtl compiler option if you are invoking the compiler with xlc_r4 or xlC_r4, or if the -qheapdebug compiler option is specified.
就是对于输出的可执行文件，启动运行时动态链接，根据公司头的解释，在加入这项时，连接器会在可执行文件和.so文件之间建立一个签名（signature），用来说明他们俩的接口，而.so文件的搜寻和载入则是由OS来负责的。

-L说明.so文件或者.a文件（静态链接库）所在的path，-l说明链接库的名称，比如 我们写 -lxxx ，连接器会去搜寻 libxxx.so 或者 libxxx.a 文件来进行处理。
