Tests failing on ubuntu server 8.04 #2

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Install ubuntu server 8.04 32bit (i used VirtualBox for that).
2. Get ACC in version 0.8.
3. Extract it and run make.

What is the expected output? What do you see instead?

Expected: All tests pass.

Actual Result:
It builds without warnings.
However, some tests fail:

result:
total=96, succeed = 89 , fail = 7
fail case :  case52 case53 case54 case58 case59 case60 case68
see log file for details

I have attached the log files.

What version of the product are you using? On what operating system?

I used ACC 0.8 on ubuntu server 8.04 32bit with gcc 4.2.4-1ubuntu4.
I also tried ACC_2009-50-30_dev : same problem.

Please provide any additional information below.

diff reports a missing hyphen ("<command line>" instead of "<command-line>").

This problem is due to the default gcc version for Ubuntu 9.10 is not 
compatible with
latest version of ACC.
Currently, the ACC compiler only support gcc 4.1 or lower.(gcc 4.2 will fail 
some
test cases)

Test Case:
-Download ACC to machine with gcc version higher than 4.1.
-untar ACC by typing "tar -xvf ACC.tar"
-make

The expected result:

...
...
testing: case93 ........pass
testing: case94_argtype ........pass
testing: case95_line ........pass
testing: case96_return_func_pointer ........pass
testing: case97_pragma ........pass
testing: case98_fp ........pass
result:
total=98, succeed = 98 , fail = 0

The actual result:

compile time errors.

Solution:
There is a temporary solution to this problem which is force the system to use 
lower
version of gcc.

Attempt #1: Changing default gcc to earlier version. 
For Ubuntu 9.04, with gcc-4.3.
Type the following command to download and install gcc-4.1. 

>sudo apt-get update
>sudo apt-get install gcc-4.1

go to ../usr/bin to force the system to use gcc-4.1

cd /usr/bin
sudo mv gcc gcc44       # save the current gcc and rename is to gcc44
sudo ln -s gcc-4.1 gcc  # force system to use gcc 4.1 by default

After all of the above progress. The default gcc for the system should be 
gcc-4.1
You can type "gcc-v" to check your gcc version.

Attempt #2: Compile with earilier version of gcc without change the default gcc.
Step 1:
Download earilier version of gcc.
Step 2:
Use the following command line.
gcc -V <version number> <.c files> 

For example:
download gcc-3.4
>sudo apt-get update
>sudo apt-get install gcc-3.4
compile main.c with gcc-3.4
>gcc -V 3.4 main.c

In this way, You should be able to run a newer version of
gcc with a flag to force behavior according
to an older version.

This problem is due to the default gcc version for Ubuntu 9.10 is not 
compatible with
latest version of ACC.

*Important: Currently, the ACC compiler only support gcc 4.1 or lower.

This issue is fixed in the latest version. You can now use any version of GCC 
to compile ACC
