GNU C Support Questions

The GNU C Development Tools are available for the following controller cards - Micro-Module, Micro-Midget, FlashModule and QuickFIRE. The tools can be used on all 32-bit Windows operating systems including Windows 98, Me, XP, 2000 and NT4.

Installing on Windows 2000 and NT 4.

Before starting to install the software make sure that you are logged on as the Administrator with full Administrator permissions. If you have already installed the software use the control panel to uninstall the software and then log in as a full Administrator and reinstall the software.

If the software is not installed with Administrator permissions it will appear to install correctly but the required registry entries will not be created. To check that the registry has been created correctly run the 'REGEDIT' program. Select the HKEY_LOCAL_MACHINE key followed by 'SOFTWARE'. Find the entry for 'Cambridge Microprocessor Systems.' Under the CEdit, Settings entry there should be a list of entries as below

(Default) REG_SZ (value not set)
Bottom REG_DWORD [value]
Left REG_DWORD [value]
ProjectName REG_SZ [current project name]
ProjectPrefix REG_SZ [current project prefix]
Right REG_DWORD [value]
TargetName REG_SZ| [current selected target]
TemplatePrefix REG_SZ [location of template files]
Top REG_DWORD [value]
Settings in [] depend on your current environment settings and may vary from one setup to the another. Top, Bottom, Left & Right define the window size and position for the CEdit window, the others are related to the project that you are currently working on. There are other registry entries, but if the ones above are not present then the installation was not done correctly and the software should be uninstalled and reinstalled.

Error Message 'Can not Start Build' on Windows NT.

The Install Shield program creates registry keys with Administrator access rights only. This means that the keys are read only to anyone except an Administrator. The following process modifies the access rights of the registry keys so that they can be changed by all users.

Log in as Administrator and install the software as normal, if you have not already done so. As the Administrator, run the registry editor program 'regedt32' (not regedit) that can be found in the WINNT\SYSTEM32 directory. Find the entry for HKEY_LOCAL_MACHINE and select the SOFTWARE entry. From the list of software, highlight the entry 'Cambridge Microprocessor Systems.' (that is the one with the full stop). From the Security Menu select the 'Permissions' option. In the list of users there will be an entry for 'Everyone'. This will be set to 'Special Access'. Highlight the 'Everyone' entry and select the type of access to be 'Full Control' from the scroll box. Finally tick the 'Replace permission on Existing Subkeys' check box and click OK. Close the registry editor down and restart the computer. This procedure will change the permissions on all of our keys so that anyone can modify them. The tools will now work for every one whatever access rights they have.

Next tick the 'Allow inheritable permissions from parent to propagate to this object' check box and click 'Advanced'. For each of the entries in the table ensure that the 'Allow inheritable permissions from parent to propagate to this object' is selected. Click 'Apply' or 'OK' and finally click 'OK' again.

If the above fixes do not resolve the problem it could be down to having a read only file on your computer. When the software is installed if there is an AUTOEXEC.BAT file present on the computer the software will add some extra directories to the PATH statement. If the AUTOEXEC.BAT file is set to READ ONLY this can not be done so the PATH does not get set up correctly. This will result in the compiler not being able to locate the executable programs. If this file is set to READ ONLY, change the permissions so that you can write to the file and add the following PATH statement -

SET PATH=%PATH%;C:\FMODULE\BIN;C:\USR\LOCAL\BIN

My program is now large and I can not add any more text.

The amount of text that you can enter in the text editor is limited. If your program is becoming too large you should split it up into more manageable source files. To add additional source files to your project click on the 'File' menu on the tool bar and select 'New'. You will then be able to select the type of file that you want to create. For assembler source files, if you are using the Motorola standard mnemonics use the extension '.S'. If the option is selected the new source file will automatically be added to the project build in the makefile.

Although Cambridge Microprocessor Systems Ltd is committed to supplying its customers with a standard well tested product, errors and bugs can always be found in even the most widely used software packages. If you find any errors or bugs please let us know by sending an email to support@cms.uk.com. All reported errors will receive a response from one of our engineers.
