Я пытаюсь следовать этому примеру curl и заставить его скомпилировать:
https://github.com/curl/curl/blob/master/docs/examples/smtp-mail.c
https://github.com/curl/curl/blob/master/docs/examples/Makefile.example
И что у меня до сих пор - границаскопировать / вставить, но я получаю сообщение об ошибке "не могу найти -lcurl"
Это то, что у меня есть для кода:
#include <stdio.h>
#include <string.h>
#include "curl-7.64.0/include/curl/curl.h"
/*
* For an SMTP example using the multi interface please see smtp-multi.c.
*/
/* The libcurl options want plain addresses, the viewable headers in the mail
* can very well get a full name as well.
*/

#define TO_ADDR "<addressee@example.net>"
#define CC_ADDR "<info@example.org>"

#define CC_MAIL "John CC Smith " CC_ADDR

И это то, что я использую дляmakefile:
TARGET = email
OBJS= smtp-mail.o
CC = gcc
CFLAGS = -c -g
LDFLAGS = -L/curl-7.64.0/lib
LIBS = -lcurl -lsocket -lnsl -lssl -lcrypto
$(TARGET) : $(OBJS)
$(CC) -o $(TARGET) $(OBJS) $(LDFLAGS) $(LIBS)
smtp-mail.o : smtp-mail.c
$(CC) $(CFLAGS) $<
Кто-нибудь знает, почему это происходит?
EDIT: я обновил пути в smtp-mail.c и make-файле:
#include "/user/jastei/Email/curl-7.58.0/include/curl/curl.h"
LDFLAGS = -L/user/jastei/Email/curl-7.58.0/lib/ -L/user/jastei/Email/curl-7.58.0/lib/vtls
Я выполнил команды:
./configure --prefix=/user/jastei/Email/curl-7.58.0 --disable-shared
make
make install
Сначала это выглядело так, как будто ничего не изменилось, однако вместо «не могу найти -lcurl» я получил это: не могу найти -lsocket
РЕДАКТИРОВАТЬ2: Относительно cmake ... когда я позвонил cmake:
/user/jastei/Email/cmake/bin/cmake CMakeLists.txt
Я получил эту ошибку:
File /user/jastei/Email/cmake/bin/headers/conf.h.in does not exist.
