Ubuntu1804编译openwrt遇到的问题

第一个错误

寻找原因行

Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/ at /home/li/OS/IBSS/IBSS-openwrt.git/staging_dir/host/bin/automake line 4160.

是staging_dir/host/bin/automake的4160行报错
因为新版的perl不再支持左大括号的使用，
进入

vim staging_dir/host/bin/automake +4160

文件删掉大括号，问题解决。

第二个错误

error: ‘gnu_inline’ attribute present on ‘libc_name_p’

.../gcc/cp/cfns.gperf: error: ‘gnu_inline’ attribute present on ‘libc_name_p’ 
.../gcc/cp/cfns.gperf: error: but not here

解决办法

参考这里
修改GGC编译目录下

./build_dir/toolchain-mipsel_mips32_gcc-4.6-linaro_uClibc-0.9.33.2/gcc-linaro-4.6-2013.05/gcc/cp/cfns.h

第四个错误

Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at kernel/timeconst.pl line 373.

这个错误是说应该省略defined().
打开

vim ./build_dir/target-mipsel_mips32_uClibc-0.9.33.2/linux-xburst_canna/linux-3.0.8/kernel/timeconst.pl +373

373行

@val = @{$canned_values{$hz}};
if (!defined(@val)) {
@val = compute_values($hz);
}
output($hz, @val);

将

if (!defined(@val))

改为

if (!(@val))

就ok了
perl版本升级到了 v5.22.1，官网因为有个BUG，该版本将defined(@array)去掉了。可以直接使用数组判断非空

编完了，没错了～～
