Q.
My program stopped operating properly after I changed the message size in the mailbox function. Why?
A.
When using the mailbox function, please set the compile option according to the mailbox size, as follows.
When specifying the message size as 32
Add -Dfar_msg=1 to the compile options.
Add c30mrlm.lib, mr30lm.lib to the link libraries in the link options.
If c30mr.lib, mr30.lib are included in the options, remove them.
1.
When specifying the message size as 16 or when not setting the send data size
If -Dfar_msg=1 is included in the compile options, remove it.
Add c30mr.lib, mr30.lib to the link libraries in the link options.
If c30mrlm.lib, mr30lm.lib are included in the options, remove them.
2.
If the above items are not set in this manner, the snd_msg system call will be called and the program will not work properly.
[How to Change the Compile Options]
For TM V.3.0 and later versions
When setting or changing the message-size specification in the MR30 configuration file, you must also add the changes
described above to the compile options in TM according to the specifications or changes.
●
When not using TM
When a makefile has been created with the makefile function in the configurator, make sure you re-execute the configuration.
This way, the compile options will be automatically revised.
