Cannot find libcrypto in Ubuntu
提问by Limavolt
I want to try one program which have makefile on it but when I put makein the shell the error was:
我想尝试一个带有 makefile 的程序，但是当我放入makeshell 时，错误是：
g++ -g -DaUNIX -I../../acroname/aInclude -I../../acroname/aSource -Wl,-rpath,. unix_aLaserDemo_Data/aLaserDemo.o unix_aLaserDemo_Data/acpLaser.o -lpthread -lcrypto -lssl -o ../../acroname/aBinary/aLaserDemo
/usr/bin/ld: cannot find -lcrypto
collect2: ld returned 1 exit status
Here is the makefile:
这是生成文件：
CC = g++
CFLAGS = -DaUNIX -I../../acroname/aInclude -I../../acroname/aSource
LFLAGS = -Wl,-rpath,.
SRC = ../../acroname/aSource
BIN = ../../acroname/aBinary
LIBS = -lpthread -lcrypto -lssl \
#LIBS = -lpthread\
-L../../acroname/aBinary -l aUtil -l aIO
OBJ = unix_aLaserDemo_Data
.PHONY : app
app : $(OBJ) $(BIN)/aLaserDemo
$(OBJ) :
mkdir $(OBJ)
$(BIN)/aLaserDemo : $(OBJ)/aLaserDemo.o $(OBJ)/acpLaser.o
$(CC) -g $(CFLAGS) $(LFLAGS) $^ $(LIBS) -o $@
$(OBJ)/aLaserDemo.o : aLaserDemo.cpp
$(CC) -c $(CFLAGS) $< -o $@
$(OBJ)/acpLaser.o : $(SRC)/acpLaser.cpp $(SRC)/acpLaser.h
$(CC) -c $(CFLAGS) $< -o $@
.PHONY : clean
clean :
rm -rf $(OBJ)
rm -f $(BIN)/aLaserDemo
I try to locate the crypto library:
我尝试找到加密库：
/usr/lib/i486/libcrypto.so.0.9.8
/usr/lib/i586/libcrypto.so.0.9.8
/usr/lib/i686/cmov/libcrypto.so.0.9.8
/usr/lib/libcrypto.so.0.9.8
What should I do to fix it?
我应该怎么做才能修复它？

I solved this on 12.10 by installing libssl-dev.

ldis trying to find libcrypto.sowhich is not present as seen in your locateoutput.
You can make a copy of the libcrypto.so.0.9.8and name it as libcrypto.so. Put this is your ld path. ( If you do not have root access then you can put it in a local path and specify the path manually )
ld正在尝试查找libcrypto.so您的locate输出中不存在的内容。您可以制作 的副本并将其libcrypto.so.0.9.8命名为libcrypto.so。把这是你的ld路径。（如果您没有 root 访问权限，则可以将其放在本地路径中并手动指定路径）
