我正在尝试编译一些名为libfprint的软件。我已经在另一台机器上成功编译了它,但是现在,在许多文件中,我收到以下错误:
tomselleck@ubuntuselleck:~/Documents/FingerBellProject/libfprint-0.5.0$ sudo make
[sudo] password for tomselleck:

有什么想法吗?谢谢!
修改
我将发布一个错误行的示例:
/* stop capturing if MAX_FRAMES is reached */
if (aesdev->blanks_count > 10 || g_slist_length(aesdev->strips) >= MAX_FRAMES) {
struct fp_img *img;
fp_dbg("sending stop capture.... blanks=%d frames=%d", aesdev->blanks_count, g_slist_length(aesdev->strips));
/* send stop capture bits */
aes_write_regv(dev, capture_stop, G_N_ELEMENTS(capture_stop), stub_capture_stop_cb, NULL);
aesdev->strips = g_slist_reverse(aesdev->strips);
img = aes_assemble(aesdev->strips, aesdev->strips_len,
FRAME_WIDTH, FRAME_HEIGHT);
g_slist_free_full(aesdev->strips, g_free);<---- Error here
aesdev->strips = NULL;
aesdev->strips_len = 0;
aesdev->blanks_count = 0;
fpi_imgdev_image_captured(dev, img);
fpi_imgdev_report_finger_status(dev, FALSE);
/* marking machine complete will re-trigger finger detection loop */
fpi_ssm_mark_completed(ssm);
/* Acquisition finished: restore default gain values */
restore_gain();
} else {
/* obtain next strip */
fpi_ssm_jump_to_state(ssm, CAPTURE_REQUEST_STRIP);
}
out:
g_free(data);
libusb_free_transfer(transfer);
}

时会发生这种情况
确保文本或标题中有原型,或者在首次使用之前将函数移动到文件的前面。

...也(括号内)不以root身份运行make
,使用sudo。这部分是因为人们可以想象在构建过程中会破坏某些重要的东西(这不是root会阻止的东西),还有一般原则,即尽可能少地生根。
如果您确实在/usr/local
等系统位置安装了某些内容,请自行构建,然后执行make -n install
并检查将要安装的位置(假设您要构建的内容具有安装目标)。如果一切正常,只有sudo make install
。
