Problems and Solutions for compiling GCC on Ubuntu

During this time, I was using software to implement a 3D graphics library. For some reason, I wanted to use something in c ++ 11. I was forced to compile gcc4.7by myself. A lot of problems were encountered in this process. After unremitting efforts, I finally compiled it successfully. Now I want to record it as a backup. I compiled it on Ubuntu11.10. the following error will be returned: 1. configure error, saying there is no gmp or something. 2. undefinedreferenceto 'lexer _ line' 3

During this time, I was using software to implement a 3D graphics library. For some reason, I wanted to use something in c ++ 11. I was forced to compile gcc4.7by myself. A lot of problems were encountered in this process. After unremitting efforts, I finally compiled it successfully. Now I want to record it as a backup.

I compiled it on Ubuntu11.10. the following error occurs:

1. configure error, saying there is no gmp or something.

2. undefined reference to 'lexer _ Line'

3. fatal error: bits/predefs. h: File or directory not found

4. ld can't find crti. o

The solution is as follows:

1. apt-get install libgmp10-dev libmp fr-dev libmp C-dev

2. apt-get install flex bison

3. 4. Compile the script on the Internet and run it directly.

The following is the script compilation process:

1. Install gmp according to steps 1 and 2 above, and so on;

2. Download the code on the official website in $ HOME/src/gcc-4.7/files/

3. Download the script in the attachment, modify PKG_SNAPSHOT_VER and TARGET_SYSTEM_TYPE, and then run it directly.

4. Follow the script running prompts to complete the final work (such as creating a symbolic link or something)

The script is as follows:

1. #! /Bin/sh
3. # Filename: build_gcc-snapshot.sh
4. # Created: 15 to Mar-2011
5. # RunAs: user or root
6. # Last Changed: 09-Oct-2011
