Sco esql generated using dynamic link library. So, when dlopen procedures mistake! ME ! ! I sco5.05 environment. I wrote one. Ec was applied to the document function, which used the informix the library functions, such as : $include Datetime.h; Tst (char 6-12) { The biggest long If (rdefmtdate (&a "yyyymmdd", p)> 0) ( Printf ( "Error!\n");       } Else{ Printf ( "Success!\n");       } } Esql translated into use. So documents. I passed the main function dlopen other Function Call. So, if : Main () { Char p[20]; Dlopen (. . . ) Dlsym (. . . )       .... } Translation operation, there are questions : Suggested that the failure to open the dynamic system, said no ecvt! When I was in the test () function to delete put rdefmtdate function, dynamic database can be deployed. I Tried many times, as long as they are in informix library function test () function, the system will be dynamic breakthrough Secretary. I have done before in other machines, there is no problem with the country, saying! Hope you can enlighten us, first of all, I would like to thank! Sco esql generated using dynamic link library. So, when dlopen procedures mistake! ME ! ! LD_LIBRARY_PATH Sco esql generated using dynamic link library. So, when dlopen procedures mistake! ME ! ! Why did you choose to transfer to the dynamic process explicit, and not directly related to the dynamic implementation of other modules compiler code generation? What is a special purpose? Sco esql generated using dynamic link library. So, when dlopen procedures mistake! ME ! ! DLL is generated when using ESQL? If ESQL generation. C, and then CC formation.
