安装旧的gdb版本

Question

我遇到了最新的问题,gdb所以我想使用较旧的一个.我在这里找到了gdb存档但是如何编译/安装其中一个以便可以使用？

根据手册,首先configure:

$ ./configure
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
[...]
configure: creating ./config.status
config.status: creating Makefile

然后make:

$ make
make[1]: Entering directory '/root/Desktop/gdb-7.7'
Configuring in ./libiberty
configure: creating cache ./config.cache
checking whether to enable maintainer-specific portions of Makefiles... no
checking for makeinfo... /root/Desktop/gdb-7.7/missing makeinfo --split-size=5000000
[...]

但它会导致错误:

remote-utils.c:436:19: error: ‘hexchars’ defined but not used [-Werror=unused-const-variable=]
 static const char hexchars[] = "0123456789abcdef";
                   ^~~~~~~~
cc1: all warnings being treated as errors
Makefile:238: recipe for target 'remote-utils.o' failed
make[4]: *** [remote-utils.o] Error 1
make[4]: Leaving directory '/root/Desktop/gdb-7.7/gdb/gdbserver'
Makefile:1345: recipe for target 'subdir_do' failed
make[3]: *** [subdir_do] Error 1
make[3]: Leaving directory '/root/Desktop/gdb-7.7/gdb'
Makefile:1018: recipe for target 'all' failed
make[2]: *** [all] Error 2
make[2]: Leaving directory '/root/Desktop/gdb-7.7/gdb'
Makefile:8611: recipe for target 'all-gdb' failed
make[1]: *** [all-gdb] Error 2
make[1]: Leaving directory '/root/Desktop/gdb-7.7'
Makefile:832: recipe for target 'all' failed
make: *** [all] Error 2

这里发现的降级程序指南也没有用,因为我总是遇到"找不到版本"的错误:

$ sudo apt-get install gdb="7.8.1"
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Version '7.8.1' for 'gdb' was not found

您正在尝试使用较新的GCC编译较旧的GDB.

这通常不起作用:较新的GCC启用新警告,GDB开发人员修复这些警告(通常在新GCC版本实际发布之前).

您应该可以使用以下命令禁用这些警告:

 ./configure 'CFLAGS=-w'

或者通过编辑生成的Makefile并修改CFLAGS那里.

其他替代品:

• 你实际上可以修复代码不产生警告(删除行436 remote-utils.c应该这样做),或
• 你可以安装相同"vintage"的旧GCC,并用它构建GDB(可能在虚拟机中).
