A Note on Using
Integrated Development Environment High-performance Embedded Workshop
|
|---|
Please take note of the following problem in using the High-performance Embedded Workshop, an integrated
development environment:
- On setting environmental variable TMP
- Products Concerned
The High-performance Embedded Workshops included with the following compiler packages are concerned:
| (1) | C compiler packages for the M32R family of MCUs
M3T-CC32R V.4.20 Release 1 and V.4.20 Release 1A |
| (2) | C compiler package for the M32C/80, and M16C/80 series of MCUs
M3T-NC308WA V.5.20 Release 1 |
| (3) | C compiler packages for the M16C/60, M16C/30, M16C/Tiny, M16C/20,
M16C/10, and R8C/Tiny series of MCUs
M3T-NC30WA V.5.20 Release 1 and V.5.30 Release 1 |
| (4) | C compiler packages for the R8C/Tiny series of MCUs (freeware Products)
M3T-NC30WA V.5.20 Release 1 (*)
M3T-NC8C V.5.30 Release 1
NOTE:
* This product's name was changed from M3T-NC30WA to M3T-NC8C on April 1, 2004.

- Description
If the directory that is set as a value of environmental variable
TMP (*) in the autoexec.bat file does not exist in the PC, any of
the following error messages appears at build:
Can't create Temporary file
Can't open Temporary file
Can't open file 'file'
NOTE:
| * |
According to the compiler package you are using, the corresponding
environmental variable name listed below must hereafter be read
for TMP.
| Compiler Package | Environmental Variable Name |
| M3T-CC32R | M32RTMP |
| M3T-NC30WA | TMP30 |
| M3T-NC308WA | TMP308 |
| M3T-NC8C | TMP8C |
|
- Workaround
Set environmental variable TMP in the PC by using High-performance Embedded Workshop as follows:
| (1) | Close the project if it is opened. |
| (2) | Open the Tool menu and select the Administration command. The Tools Administration dialog box appears. |
| (3) | In the Toolchains folder in the Registered Components list, click the "+" sign to view the components included. |
| (4) | Select Renesas xx Standard Toolchain. Here xx denotes the name of an MCU family or series. |
| (5) | Click the Properties button. The Renesas xx Standard Toolchain dialog box opens. |
| (6) | Click the Environment tab to display the Environmental Variables page. |
| (7) | Click the Add button. The Environmental Variable dialog box opens. Then, type TMP in the Variable text box and the directory name in the Value text box. |
| (8) | Click the OK button to close all the dialog boxes. |
- Schedule of Fixing the Problem
In our next release of the compiler packages concerned, we plan to fix
this problem in such a way that the High-performance Embedded Workshop sets environmental variable
TMP automatically.
