Из-за необходимости проекта мы изменили ядро / цепной код / шим из ткани 1.0.0.Древовидная структура shim:
shim
├── chaincode.go
├── handler.go
├── inprocstream.go
├── interfaces.go
├── java
│ └── ···
├── mockstub.go
├── mockstub_test.go
├── response.go
├── myxxxutil.go
├── shim_test.go
└── myxxx.go
Для некоторых из этих функций требуется cgo, который написан на c ++, есть фрагмент кода:
//myxxx.go
package shim
/*
#cgo CFLAGS: -I/opt/xxxsrc
#cgo LDFLAGS: -L/usr/lib -lmyxxx
#include "interface.hpp"
#include <stdlib.h>
*/
import "C"
func SomeFucn(){
··· //the C++ source code is in /opt/xxxsrc folder，so is interface.hpp file，the libmyxxx.so file is in /usr/lib folder
}
Я использовал makeКоманда docker для создания однорангового образа на основе hyperledger / fabric-baseimage: x86_64-0.3.1 в каталоге Fabric.Этот hyperledger / fabric-baseimage: x86_64-0.3.1 был изменен мной.Я поставил libmyxxx.так что файл в папку / usr / lib этого "baseimage", и поместите код С ++ soure в / opt / xxxsrc, тогда журнал выполнения:
Building build/docker/bin/peer
(the docker command line is：

Я уже пытался добавить путь (/ usr/ lib) в файле /etc/ld.so.conf и выполнили команду «ldconfig», а также попытались добавить путь к переменным среды LD_LIBRARY_PATH и LIBRARY_PATH, проблема все еще появляется, поэтому я хотел бы спросить, есть ли какое-либо решение дляпроблема, спасибо
