How to set compiler when cross? #77

Closed feifei17 closed 8 years ago

feifei17 commented 8 years ago

hello, I use makeme to compile appweb6.2.1,but i can't set compiler when cross, I config with this:

CC=/opt/arm-2014.05/bin/arm-none-linux-gnueabi-gcc ./configure --with sqlite --set esp.depends sqlite --with ejscript --without watchdog --platform linux-arm-release --set compiler.hasDynLoad=true

but the linux-arm-release/platform.me like this:

platform: {
  8         name: "linux-arm-release",
  9         os: "linux",
 10         arch: "arm",
 11         like: "unix",
 12         dist: "ubuntu",
 13         profile: "release",
 14         dev: "linux-x86-release",
 15         cross: true,
 16         "arch-map": {
 17             x86: "i686",
 18             x64: "x86_64",
 19         },
 20     },
compiler: {
 67             hasAtomic: false,
 68             hasMmu: false,
 69             hasPam: false,
 70             hasAtomic64: false,
 71             hasDoubleBraces: false,
 72             hasDynLoad: false,
 73             hasLibEdit: false,
 74             hasLibRt: false,
 75             hasMtune: false,
 76             hasStackProtector: false,
 77             hasSync: false,
 78             hasSync64: false,
 79             hasSyncCas: false,
 80             hasUnnamedUnions: false,
 81             warnUnused: false,
 82             warn64to32: false,
 83         },

More detail please. What did you expect and what did you get? Please include compile output.

I want to use mprLoadModule in my app , and my app running ok in local system, but in ARM error. output: mprLoadModule: initModule failed Product built without the ability to load modules dynamically

in my appweb.conf like this:LoadModule initModule libmod_init

compile ok,output:

MakeMe tests the compiler to see if it has support for dynamic library loading. But this is hard to do for some embedded systems.

Edit build//platform.me and change the setting for settings.compiler.hasDynLoad. Then edit build//inc/me.h and change 

#define ME_COMPILER_HAS_DYN_LOAD 1

Generally folks build static without dynamic modules on embedded targets.

Thank you very much!

As your saied, I modified the hasDynLoad to true and ME_COMPILER_HAS_DYN_LOAD to 1 then,when compile some files the compiler like this: [Run] arm-linux-gnueabi-gcc -o build/linux-arm-release/bin/appman -g -rdynamic -Wl,--enable-new-dtags -Wl,-rpath,$ORIGIN/ -Lbuild/linux-arm-release/bin "build/linux-arm-release/obj/watchdog.o" -lmpr -lmpr-mbedtls -lmbedtls -lpthread -lm -lmpr -lmpr-mbedtls -lmbedtls -lpthread -lm me: ERROR: Building target watchdog

Command failure: build/linux-arm-release/bin/libmpr.so：对‘dlsym’未定义的引用 build/linux-arm-release/bin/libmpr.so：对‘dlerror’未定义的引用 build/linux-arm-release/bin/libmpr.so：对‘dlopen’未定义的引用 build/linux-arm-release/bin/libmpr.so：对‘dlclose’未定义的引用 collect2: 错误： ld 返回 1

then ,I manually add options “-ldl” and complie like this: fei@fei-wk:~/appweb/appweb-6.2.1$ arm-linux-gnueabi-gcc -o build/linux-arm-release/bin/appman -g -rdynamic -Wl,--enable-new-dtags -Wl,-rpath,$ORIGIN/ -Lbuild/linux-arm-release/bin "build/linux-arm-release/obj/watchdog.o" -lmpr -lmpr-mbedtls -lmbedtls -lpthread -lm -lmpr -lmpr-mbedtls -lmbedtls -lpthread -lm -ldl

and the compiler looks work well. but ,when running on the ARM board still error, like this: [root@IoT9608 srv]# ls bin/ appman* http* libmod_init.so* libsscom.so appweb* libappweb.so* libmod_io.so* libzlib.so appweb-ejs* libejs.so* libmod_sms.so* makerom appweb-ejsc* libesp.so* libmod_zig.so* roots.crt ca.crt libhttp.so* libmpr-mbedtls.a self.crt ca.key libmbedtls.a libmpr-version.a self.key ec.crt libmod_com.so* libmpr.so* test.crt ec.key libmod_ejs.so* libpcre.so* test.key ejs.mod libmod_gps.so* libsnmp_nms.so* vcvars.bat esp-compile.json libmod_hio.so* libsql.so [root@IoT9608 srv]# bin/appweb --config appweb.conf -v bin/appweb: error while loading shared libraries: libappweb.so: cannot open shared object file: No such file or directory [root@IoT9608 srv]#

so,I think: When I was not modified hasDynLoad and ME_COMPILER_HAS_DYN_LOAD , the appweb can running(but can't loadMods),Whether I can recognize the powder at that time the appweb can load the libappweb.so ? but why can't load lib myself ? such as libmod_init.so ?

I'm trying to compile static, Thank you very much!
