我遇到了最新gdb
的问题,所以我想使用较旧的版本。我找到了gdb
存档here但是如何编译/安装其中一个以便可以使用它?
根据manual,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";
^~~~~~~~

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
有关降级程序的指南here也没有帮助,因为我总是找不到"找不到版本"错误:
$ sudo apt-get install gdb="7.8.1"

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)。
您应该能够通过以下方式禁用这些警告:
./configure 'CFLAGS=-w'
或通过编辑生成的Makefile并修改那里的CFLAGS
。
其他替代方案:
remote-utils.c
的第436行应该这样做)或答案 1 :(得分:1)
您可以使用以下命令检查与错误相关的配置标志:
./configure --help | grep error
--enable-werror enable -Werror in bootstrap stage2 and later
因此,您可以禁止将警告视为错误:
./configure --disable-werror
