gcc - jni call involving open cobol dlls -

-

i trying invoke existing cobol application using jni. cobol application structure follows.

c-wrapper(main)-->cobolprogram -> several dyn(.so) , static  called modules

the existing cobol application involves several statically called subprograms(cobol) , many dynamic(cobol) ones.

jni invocation of application ok, not locate , invoke cobol dynamic sub modules.

modified application structure (for jni) follows:

java class --> libjni.so --> appl.so

i verified cob_library_path , ld_library_path environment variables before call, seems fine.

following error message got in case dynamic modules.

libcob:  ....<module>.so: undefined symbol: cob_save_call_params

i use 64 bit , 1.1.0 on linux. gcc used create binary using c output of cobc command

this issue can resolved specifying -lcob linkage option(when using gcc). gcc command used create binary contained option, mistakenly placed in between target , source file, not in effect. execution of dll without jni invocation, somehow not require -lcob option, jni invocation requires -lcob linkage option.

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
