|
|
|
|
1
|
path
|
Specifies a storage directory for the execution file.
|
[V3.05 or earlier] Specification cannot be omitted.
|
|
2
|
BIN_RX
|
Specifies the directory in which ccrx is stored.
|
<ccrx storage directory>
[V3.05 or earlier] Specification cannot be omitted when the lbgrx command is used.
|
|
3
|
ISA_RX *1
|
Selects an instruction-set architecture.
<Instruction-set architectures>
RXV1
RXV2
RXV3 [V3.00.00 or later]
|
No value is set when the specification is omitted.
|
|
4
|
INC_RX
|
Specifies a directory in which an include file of the compiler is stored.
|
<ccrx storage directory>
\..\include
|
|
5
|
INC_RXA
|
Specifies a directory in which an include file of the assembler is stored.
|
No value is set when the specification is omitted.
|
|
6
|
TMP_RX
|
Specifies a directory in which a temporary file is generated.
|
OS settings
|
|
7
|
HLNK_LIBRARY1
HLNK_LIBRARY2
HLNK_LIBRARY3
|
Specifies a default library name for the optimizing linkage editor. Libraries which are specified by a library option are linked first. Then, if there is an unresolved symbol, the default libraries are searched in the order of 1, 2, 3.
|
No value is set when the specification is omitted.
|
|
8
|
HLNK_TMP
|
Specifies a folder in which the optimizing linkage editor generates temporary files. If HLNK_TMP is not specified, the temporary files are created in the current folder.
|
No value is set when the specification is omitted.
|
|
9
|
HLNK_DIR
|
Specifies an input file storage folder for the optimizing linkage editor. The search order for files which are specified by the input or library option is the current folder, then the folder specified by HLNK_DIR.
However, when a wild card is used in the file specification, only the current folder is searched.
|
No value is set when the specification is omitted.
|
|
10
|
CPU_RX *1
|
Specifies the CPU type.
<CPU types>
RX600
RX200
|
No value is set when the specification is omitted.
|
*1) When both ISA_RX and CPU_RX are defined, ISA_RX takes precedence.
