我试图为debian 8重新编译我的软件，但是我遇到了libgssappi这个奇怪的问题，拒绝与任何东西联系。
>~/torque_github$ gcc test.c -lgssapi
/usr/bin/ld: cannot find -lgssapi
collect2: error: ld returned 1 exit status
该库存在于系统中，如下所示：
>~/torque_github$ /sbin/ldconfig -p | grep gssapi
libgssapi_krb5.so.2 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgssapi_krb5.so.2
libgssapi.so.3 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgssapi.so.3
答案 0 :(得分：1)
在我的Debian / Jessie / x86-64系统上，/usr/lib/x86_64-linux-gnu/libgssapi_krb5.so包提供dpkg -S（根据libkrb5-dev），/usr/lib/x86_64-linux-gnu/libgssapi.so.3提供libgssapi3-heimdal libgssapi*dev包（我没有任何sudo aptitude install libkrb5-dev libgssapi3-heimdal包）。
您可能应该安装它们（使用pkg-config命令），并使用krb5-gssapi和gcc -Wall -g $(pkg-config --cflags krb5-gssapi) \
test.c \
$(pkg-config --libs krb5-gssapi) \
-o myprog
来获取编译和链接标记。
test.c （如果某些API发生了变化，您可能需要更改#include <krb5/krb5.h>源代码;或许您需要gcc -v）
您甚至可以使用gcc代替上面的gcc。
请记住，gcc的参数顺序非常重要。您的初始问题有不同的顺序（这足以使-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSLog(@"%@",userInfo);
NSString *msg=[userInfo objectForKey:@"message"];
//Application is Running
if ( application.applicationState == UIApplicationStateActive ){
if ([[userInfo objectForKey:@"id"]isEqualToString:@"1"]) {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
YourViewController *obj = [[YourViewController alloc]initWithNibName:@"YourViewController" bundle:nil];
nav = [[UINavigationController alloc]initWithRootViewController:obj];
[self.nav setNavigationBarHidden:YES];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
}
else if ([[userInfo objectForKey:@"id"]isEqualToString:@"2"]) {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
YourViewController *obj = [[YourViewController alloc]initWithNibName:@"YourViewController" bundle:nil];
nav = [[UINavigationController alloc]initWithRootViewController:obj];
[self.nav setNavigationBarHidden:YES];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
}
}
//when Application in Background
else{
if ([[userInfo objectForKey:@"id"]isEqualToString:@"1"]) {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
YourViewController *obj = [[YourViewController alloc]initWithNibName:@"YourViewController" bundle:nil];
nav = [[UINavigationController alloc]initWithRootViewController:obj];
[self.nav setNavigationBarHidden:YES];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
}
else if ([[userInfo objectForKey:@"id"]isEqualToString:@"2"]) {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
YourViewController *obj = [[YourViewController alloc]initWithNibName:@"YourViewController" bundle:nil];
nav = [[UINavigationController alloc]initWithRootViewController:obj];
[self.nav setNavigationBarHidden:YES];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
}
}
}
失败）！
