1、問題
root@ubuntu01:/home/software/PopLDdecay# ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... no checking for mawk... mawk checking whether make sets $(MAKE)... no checking for gawk... (cached) mawk checking for g++... no checking whether the C++ compiler works... no configure: error: in `/home/software/PopLDdecay': configure: error: C++ compiler cannot create executables See `config.log' for more details
2、測試gcc c++
root@ubuntu01:/home/software/PopLDdecay# gcc --version -bash: gcc: command not found root@ubuntu01:/home/software/PopLDdecay# c++ --version -bash: c++: command not found
3、安裝gcc、c++編譯器
root@ubuntu01:/home/software/PopLDdecay# apt install build-essential
報錯如下：
解決方法：
root@ubuntu01:/home/software/PopLDdecay# apt update
4、再次安裝gcc、c++編譯器
root@ubuntu01:/home/software/PopLDdecay# apt install build-essential
沒有問題。
5、測試gcc、c++
