我在使用最新的gdb时遇到问题，因此我想使用较旧的gdb。我找到了configure存档文件here，但是如何编译/安装其中一个文件以便可以使用？
根据manual，第一个make:
$ ./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ojit_code:
$ 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
[...]
但这会导致错误:
remote-utils.c:436:19: error: ‘hexchars’ defined but not used [-Werror=unused-const-variable=]
static const char hexchars[] = "0123456789abcdef";
^~~~~~~~

make[1]: Leaving directory '/root/Desktop/gdb-7.7'
Makefile:832: recipe for target 'all' failed

关于降级程序的指南发现here也无济于事，因为我总是遇到“找不到版本”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
最佳答案
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会启用新的警告，而GDB开发人员会修复这些警告(通常在实际发布新的GCC版本之前)。
您应该能够通过以下方式禁用这些警告:
./configure 'CFLAGS=-w'
或者通过编辑生成的Makefile并在此处修改
CFLAGS来实现。其他替代方案:
remote-utils.c的第436行来做到这一点)，或者关于linux - 安装较旧的gdb版本，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/41556448/
