Install Insight6.8.1 on Ubuntu

1. insighthttp: // response

1. insight http://sourceware.org/insight/downloads.php

2. decompress the package to Ubuntu. The decompressed directory is as follows:

/Home/haowei/Downloads/insights-6.8-1

3. Go to the insight-6-8-1 directory and run the./configure command.

4. When executing the make command, an exception occurs during compilation:

1. C0: warning being treated as errors
2. Linux-nat.c: In function'Linux _ nat_info_proc_cmd':
3. Linux-nat.c: 2879: error: ignoringReturnValue'Fgets', Declared with attribute warn_unused_result

View the gdb/linux-nat.c function 'linux _ nat_info_proc_cmd ':

This is because the fgets method called in this function does not define the return value.

The source code is as follows:

1. If(Procfile = fopen (fname1,"R"))! = NULL)
2. {
3. Fgets (buffer,Sizeof(Buffer), procfile );
4. Printf_filtered ("Required line = '% s' \ n", Buffer );
5. Fclose (procfile );
6. }

Modified code:

1. If(Procfile = fopen (fname1,"R"))! = NULL)
2. {
3. Char* P = fgets (buffer, sizeof (buffer), procfile );
4. Printf_filtered ("Required line = '% s' \ n", Buffer );
5. Fclose (procfile );
6. }

There are several similar errors involved: write, getcwd, dup...

The specific file will be prompted when you execute make.

You can call these methods to define a return value during modification:

Int p = write (....);

Char * p = getcwd (....);

Int p = dup (...);

Note that the definitions of these variables should be placed at the beginning of the function.

There is also a gdb/eval. c class. The code compilation error is as follows:

IntSubscript_array [MAX_FORTRAN_DIMS];

This array is not initialized. You can initialize this array and compile it as follows:

1. If(Nargs> MAX_FORTRAN_DIMS)
2. Error (_("Too upload subscripts for F77 (% d Max )"), MAX_FORTRAN_DIMS );
4. Memset (& subscript_array,0, Sizeof (subscript_array ));

5. After executing make, run sudo make install to complete the installation.

Appendix. This is what insight runs after I compile the program:
